mt76_queue_entry has alreay one bool variable, adding new one will
not increase it's size. Removing ->done filed from mt76u_buf will

Create software MT_TXQ_PSD queue for USB and map it to MT_TXQ_VO

Since we sent PS buffered frames via beacon memory we need to make

Program beacons data and PS buffered frames on TBTT work for USB.
We do not have MT_TXQ_PSD queue available via USB endpoints. The way
we can send PS broadcast frames in timely manner before PS stations go
sleep again is program them in beacon data area. Hardware do not modify
those frames since TXWI is properly configured. mt76x02_mac_set_beacon()
already handle this and free no longer used frames.

If the MT_TXD3_SN_VALID flag is not set in the tx descriptor, the hardware
assigns the sequence number. However, the rest of the code assumes that the
sequence number specified in the 802.11 header gets transmitted.
This was causing issues with the aggregation setup, which worked for the
initial one (where the sequence numbers were still close), but not for
further teardown/re-establishing of sessions.
Additionally, the overwrite of the TID sequence number in WTBL2 was resetting
the hardware assigned sequence numbers, causing them to drift further apart.
Fix this by using the software assigned sequence numbers

q->tail can be safely updated without locking, because there is no
concurrent access. If called from outside of the tasklet (for flushing),
the tasklet is always disabled.
q->queued can be safely read without locking, as long as the decrement
happens within the locked section.
This patch allows cleaning up tx packets outside of the section that holds
the queue lock for improved performance
