Subject: [PATCH net v2 03/21] cfg80211: set .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")
Fixes: 80a3511d70e8 ("cfg80211: add debugfs HT40 allow map")
Signed-off-by: Taehee Yoo <ap420073@...il.com>
