Currently, wcn36xx only asks for a TX BA session if it has
already established one for RX. Thus, two wcn36xx devices cannot
do a-mpdu between themselves since they both wait for the other
to go first. Fix this by starting a BA session after a few QoS
data frames have been sent to a STA.

The pdu is part of the buffer descriptor, so it makes
sense that one function would fill both. Also, passing
the whole skb instead of just the header pointer to the
set_tx_data function paves the way for using its fields
for ampdu setup inside set_tx_data().

wcn36xx currently sends an incorrect sequence number into the BA session
setup firmware command: it should be saving or updating the ssn in the
TX_START ampdu_action callback instead of waiting until TX_OPERATIONAL.
However, we can sidestep the issue by letting the hardware generate the
sequence numbers for QoS frames, as is done in prima, so do that.

bd->tx_comp is a single bit in a bitfield, so assigning
"info->flags & IEEE80211_TX_CTL_REQ_TX_STATUS" only happens
to work because TX_STATUS is defined to BIT(0); if it were
any other bit this assignment would fail.

The purpose of this housekeeping is to make some room for
VHT flags. The radiotap vendor fields weren't in use.
