Previously, each bus type was responsible for freeing the firmware
structure, but some did that badly. Move responsibility for freeing
firmware into firmware.c so that it's done once and correctly, instead
of happening in multiple places in bus-specific code.
This fixes a use-after-free bug found by Dr. H. Nikolaus Schaller where
the SDIO code forgot to NULL priv->helper_fw after freeing it.

Polling TX statuses too frequently has two negative effects. First is
randomly peek CPU usage, causing overall system functioning delays.
Second bad effect is that device is not able to fill TX statuses in
H/W register on some workloads and we get lot of timeouts like below:
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping
This not only cause flood of messages in dmesg, but also bad throughput,
since rate scaling algorithm can not work optimally.
In the future, we should probably make polling interval be adjusted
automatically, but for now just increase values, this make mentioned
problems gone.

The regression was introduced in the following commit:
0967e01e8e
"ath5k: make use of the new rate control API"
ath5k_tx_frame_completed saves the intended per-rate retry counts before
they are cleared by ieee80211_tx_info_clear_status, however at this
point the information in info->status.rates is incomplete.
This causes significant throughput degradation and excessive packet loss
on links where high bit rates don't work properly.
Move the copy from bf->rates a few lines up to ensure that the saved
retry counts are updated, and that they are really cleared in
info->status.rates after the call to ieee80211_tx_info_clear_status.

Since we set IEEE80211_HW_QUEUE_CONTROL, we can let
mac80211 do the queue assignement and don't need to
override its decisions.
While reassiging the same values is harmless of course,
it triggered a WARNING when iwlwifi and mac80211 came
to different conclusions. This happened when mac80211 set
IEEE80211_TX_CTL_SEND_AFTER_DTIM, but didn't route the
packet to the cab_queue because no stations were asleep.
iwlwifi should not override mac80211's decicions for
offchannel packets and packets to be sent after DTIM,
but it should override mac80211's decision for AMPDUs
since we have a special queue for them. So for AMPDU,
we still override info->hw_queue by the AMPDU queue.
This avoids:

The firmware always expects the Coex Mode to be set.
Moreover, the firmware expects bit 0 is the valid bits to
be set all the times.
I misunderstood the API and didn't set these bits when
commands are sent to update the paramters of the Coex. As
a result, the firmware understood that the BT Coex was
disabled (Coex mode = 0) and ignored all the updates (valid
bit 0 clear).

This is a batch of updates intended for the 3.13 stream...
The biggest item of interest in here is wcn36xx, the new mac80211

Regarding the mac80211 bits, Johannes says:
"We have an assortment of cleanups and new features, of which the
biggest one is probably the channel-switch support in IBSS. Nothing
else really stands out much."
On top of that, the ath9k and rt2x00 get a lot of update action from

On top of those...
