[PATCH net 001/117] mac80211: set .owner to THIS_MODULE in debugfs_netdev.c

From

Also in
linux-bluetooth, linux-wireless
If THIS_MODULE is not set, the module would be removed while debugfs is
being used.
It eventually makes kernel panic.

Fixes: e9f207f0ff90 ("[MAC80211]: Add debugfs attributes.")
