Tetsuo Handa 3598cb6e18 wifi: mac80211: do not abuse fq.lock in ieee80211_do_stop() 
lockdep complains use of uninitialized spinlock at ieee80211_do_stop() [1],
for commit f856373e2f ("wifi: mac80211: do not wake queues on a vif
that is being stopped") guards clear_bit() using fq.lock even before
fq_init() from ieee80211_txq_setup_flows() initializes this spinlock.

According to discussion [2], Toke was not happy with expanding usage of
fq.lock. Since __ieee80211_wake_txqs() is called under RCU read lock, we
can instead use synchronize_rcu() for flushing ieee80211_wake_txqs().
