mac80211: Do not free net device after it is unregistered.
The error path in ieee80211_register_hw() may call the unregister_netdev()
and right after it - the free_netdev(), which is wrong, since the
unregister releases the device itself.
So the proposed fix is to NULL the local->mdev after unregister is done
and check this before calling free_netdev().
I checked - no code uses the local->mdev after unregister in this error
path (but even if some did this would be a BUG).
