There exist 12 802.11b/g rates, but mwl8k supports two additional
(non-standard) rates, and includes those rates in rate bitmasks and
in its internal rate table that hardware rate indices index.
Commit "mwl8k: report rate and other information for received frames"
added one of the nonstandard rates to the mwl8k_rates table to make
the OFDM rates in the table line up with the rate indices that are
reported in the receive descriptor (so that we can just simply copy
the receive descriptor rate index into ieee80211_rx_status::rate_idx)
and bumped MWL8K_IEEE_LEGACY_DATA_RATES from 12 to 13, but this
screwed up the UPDATE_STADB command struct layout, as it also uses
that define, for its legacy_rates array.
To avoid having to convert rate indices and legacy rate bitmaps (e.g.
ieee80211_bss_conf::basic_rates) between the 12-rate mac80211 format
and the 14-rate mwl8k format, we'll report all 14 rates in our wiphy's
band, but filter out the nonstandard ones e.g. in the case of the
UPDATE_STADB command which only accepts 12 rates.
In the commands that accept 14 rates (SET_AID, SET_RATE), replace the
use of the MWL8K_RATE_INDEX_MAX_ARRAY define in the command struct by
the constant 14, to make it clearer that these commands accept 14 rates.

The MCS bitmaps in the SET_RATE command structure were of the wrong
size, due to use of the wrong define for the array length. Just
hardcode the lengths as 16, and do the same for the MCS bitmaps in
other command structures.

Not only ps_sdata but also IEEE80211_CONF_PS is to be considered
before restoring PS in scan_ps_disable(). For instance, when ps_sdata
is set but CONF_PS is not set just because the dynamic timer is still
running, a sw scan leads to setting of CONF_PS in scan_ps_disable
instead of restarting the dynamic PS timer.
Also for the above case, a null data frame is to be sent after
returning to operating channel which was not happening with the
current implementation. This patch fixes this too.

hwsim testing has revealed that when the MLME
recalculates the idle state of the device, it
sometimes does so before sending the final
deauthentication or disassociation frame. This
patch changes the place where the idle state
is recalculated, but of course driver transmit
is typically asynchronous while configuration
is expected to be synchronous, so it doesn't
fix all possible cases yet.

This reverts commit f20941f334.
Sergei Shtylyov notes "You call min() on uncomparables [in

adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second
argument will always "win" as a minimal one"
Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related
to mwdma_clip_to_pio(). The function can return values between 0 and
4 which obviously won't work well for the new code below for values
>2 (i.e. resulting in out-of-bounds array access for the common-case
of dev->pio_mode == XFER_PIO_4)."
