ath11k: Avoid NULL ptr access during mgmt tx cleanup
Currently 'ar' reference is not added in skb_cb during
WMI mgmt tx. Though this is generally not used during tx completion
callbacks, on interface removal the remaining idr cleanup callback
uses the ar ptr from skb_cb from mgmt txmgmt_idr. Hence
fill them during tx call for proper usage.
Also free the skb which is missing currently in these
callbacks.
