mt76: mt76u: add queue parameter to mt76u_rx_urb_alloc
Add mt76_queue parameter to mt76u_rx_urb_alloc signature since this
routine will be used to allocate urbs for mcu hw queue used by new
chipset generation (e.g. mt7663u). Check sg_max_size in in
mt76u_urb_alloc in order to use linear urb for mcu queue
