Subject: [PATCH net 017/117] mac80211/cfg80211: set DEBUGFS_READONLY_FILE.owner to THIS_MODULE

If THIS_MODULE is not set, the module would be removed while debugfs is
being used.
It eventually makes kernel panic.

Fixes: 1ac61302dcd1 ("mac80211/cfg80211: move wiphy specific debugfs entries to cfg80211")
