wifi: ath12k: Avoid NULL pointer access during management transmit cleanup

Browse source

[ Upstream commit 054b5580a3 ]

Currently 'ar' reference is not added in skb_cb.
Though this is generally not used during transmit completion
callbacks, on interface removal the remaining idr cleanup callback
uses the ar pointer from skb_cb from management txmgmt_idr. Hence fill them
during transmit call for proper usage to avoid NULL pointer dereference.
