mac80211: improve cleanup when leaving mesh
It is not necessary to stop the mesh beacon in the mac80211 ndo_stop
handler, since cfg80211 has already left the mesh on NETDEV_GOING_DOWN
notification.
Also some improvements to ieee80211_stop_mesh():
- flush mpath entries.
- flush sta entries per-sdata so we don't remove entries belonging to
other vifs on the same hw.
