[PATCH 2/3] mt76: usb: fix hw initialization sequence

[Lorenzo Bianconi]

mt76u_alloc_queues need to be called before mt76u_mcu_init_rx
since it initializes rx_page_lock spinlock used in mt76u_buf_alloc
routine.

Fixes: b11e19694dc9 ("mt76x0: add ieee80211_ops ops pointer to
mt76x0_alloc_device signature")
