Felix Fietkau 2a092e2b1d mt7603: fix per-rate retry accounting 
Each rate retry slot takes up MT7603_RATE_RETRY tries, and cannot be altered
based on mac80211 provided rate retry counts.

Felix Fietkau bce700dd0c mt7603: fix signal strength reporting on single-stream devices 
The second chain value is 0 if the second chain is disabled, which
would make the reported signal strength 0 as well.

during the ieee80211_tx_status call.
