Subject: [PATCH 5.1 087/405] mt76: remove mt76_queue dependency from tx_queue_skb function pointer
[ Upstream commit 89a37842b0c13c9e568bf12f4fcbe6507147e41d ]
Remove mt76_queue dependency from tx_queue_skb function pointer and
rely on mt76_tx_qid instead. This is a preliminary patch to introduce
mt76_sw_queue support
