net: ethernet: mtk_wed: get rid of queue lock for tx queue

Browse source

Similar to MTK Wireless Ethernet Dispatcher (WED) MCU rx queue,
we do not need to protect WED MCU tx queue with a spin lock since
the tx queue is accessed in the two following routines:
- mtk_wed_wo_queue_tx_skb():
  it is run at initialization and during mt7915 normal operation.
  Moreover MCU messages are serialized through MCU mutex.
- mtk_wed_wo_queue_tx_clean():
  it runs just at mt7915 driver module unload when no more messages
  are sent to the MCU.

Remove tx queue spinlock.
