wifi: mt76: set the EOSP bit in the QoS header of the last released frame

Browse source

When the driver implements .release_buffered_frames, mac80211 leaves the
U-APSD signalling entirely to the driver: "In this case it is also
responsible for setting the EOSP flag in the QoS header of the frames"
(include/net/mac80211.h). Only IEEE80211_TX_STATUS_EOSP was being set,
which merely ends the service period inside mac80211, so on air the
service period was never terminated. Clients that wait for EOSP before
going back to doze keep the SP open and stop triggering, which stalls all
downlink traffic for that station.

Set the wire EOSP bit on the last frame of a U-APSD service period.
EOSP has no meaning for a PS-Poll response, so pass the release reason
down and leave those frames alone.
