wifi: ath11k: fix gtk offload status event locking

The ath11k active pdevs are protected by RCU but the gtk offload status event handling code calling ath11k_mac_get_arvif_by_vdev_id() was not marked as a read-side critical section.

Mark the code in question as an RCU read-side critical section to avoid any potential use-after-free issues.

Compile tested only.
