wifi: ath11k: Cleanup mac80211 references on failure during tx_complete
When a function is using functions from mac80211 to free an skb then it
should do it consistently and not switch to the generic dev_kfree_skb_any
(or similar functions). Otherwise (like in the error handlers), mac80211
will will not be aware of the freed skb and thus not clean up related
information in its internal data structures.
Not doing so lead in the past to filled up structure which then prevented
new clients to connect.

Fixes: 6257c702264c ("wifi: ath11k: fix tx status reporting in encap offload mode")
