wifi: mac80211: transmit deauth only if link is available
There's an issue in that when we disconnect from an AP
due to the AP switching to an unsupported channel, we
might not tell the driver about this before we try to
send the deauth. If the underlying implementation has
detected the quiet CSA, this may cause issues if this
is the only active link. Avoid this by transmitting
(and flushing) the deauth only when there's an active
link available that's not affected by quiet CSA.
Since this introduces link->u.mgd.csa_blocked_tx and we
no longer check sdata->csa_blocked_tx for the TX itself
also rename the latter to csa_blocked_queues.
Fixes: 6f0107d195a8 ("wifi: mac80211: introduce a feature flag for quiet in CSA")
