3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Johannes Berg <[email protected]> Commit 5b36ebd8249f403c7edf7cf68d68e9a0d0f55243 upstream. In some cases when disconnecting after (or during?) CSA the queues might not recover, and then the only way to recover is reloading the module. Fix this by always unblocking the queue CSA reason when disconnecting.
