wifi: iwlwifi: mvm: handle BA session teardown in RF-kill
[ Upstream commit 4d08c0b3357cba0aeffaf3abc62cae0c154f2816 ]
When entering RF-kill, mac80211 tears down BA sessions, but
due to RF-kill the commands aren't sent to the device. As a
result, there can be frames pending on the reorder buffer or
perhaps even received while doing so, leading to warnings.
Avoid the warnings by doing the BA session teardown normally
even in RF-kill, which also requires queue sync.
