mac80211: fix mesh deadlock
The patch "cfg80211/mac80211: use cfg80211 wdev mutex in
mac80211" introduced several deadlocks by converting the
ifmsh->mtx to wdev->mtx. Solve these by:
1. drop the cancel_work_sync() in ieee80211_stop_mesh().
Instead make the mesh work conditional on whether the mesh
is running or not.
2. lock the mesh work with sdata_lock() to protect beacon
updates and prevent races with wdev->mesh_id_len or
cfg80211.
