wifi: rtw88: usb: fix priority queue to endpoint mapping

The RTW88 chipsets have four different priority queues in hardware. For
the USB type chipsets the packets destined for a specific priority queue
must be sent through the endpoint corresponding to the queue. This was
not fully understood when porting from the RTW88 USB out of tree driver
and thus violated.

This patch implements the qsel to endpoint mapping as in
get_usb_bulkout_id_88xx() in the downstream driver.

Without this the driver often issues "timed out to flush queue 3"
warnings and often TX stalls completely.
