Subject: [PATCH net v2 13/21] ath10k: 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: 90174455ae05 ("ath10k: add support to configure pktlog filter")
Fixes: 63fb32df9786 ("ath10k: add debugfs entry to configure quiet period")
Fixes: 844fa5722712 ("ath10k: debugfs file to enable Bluetooth coexistence feature")
Fixes: 348cd95c8196 ("ath10k: add debugfs entry to enable extended tx stats")
Fixes: cc61a1bbbc0e ("ath10k: enable debugfs provision to enable Peer Stats feature")
