If mac80211 attempts to set a key for an interface before this assignment, the driver caches the key. Once the interface is created, the driver installs the cached key to the hardware. This sequence is exemplified in mesh mode operation where the group key is set before channel assignment. However, in ath12k_mac_update_key_cache(), after caching the key, due to incorrect logic, it is deleted from the cache during the subsequent loop iteration. As a result, after the interface is created, the driver does not find any cached key, and the key is not installed to the hardware which is wrong. This leads to issue in mesh, where broadcast traffic is not encrypted over the air. Fix this issue by adjusting the logic of ath12k_mac_update_key_cache() properly.

Fix this warning by moving wiphy_unregister() after wilc_netdev_cleanup() is nominal paths (ie: driver removal). wilc_netdev_cleanup() ordering is left untouched in error paths in probe function because net device is not registered in those paths (so the warning can not trigger), yet the wiphy can still be registered, and we still some cleanup steps from wilc_netdev_cleanup().
