[PATCH 5.10 1/1] mt76: fix mt7615_init_tx_queues() return value

[Nikita Zhandarovich]

mt7615_init_tx_queues() returns 0 regardless of how final
mt7615_init_tx_queue() performs. If mt7615_init_tx_queue() fails (due to
memory issues, for instance), parent function will still erroneously
return 0.

This change takes into account ret value of mt7615_init_tx_queue()
when finishing up mt7615_init_tx_queues().
