wifi: mt76: mt7996: send the STA_REC before the per-station VoW setup

Browse Source 
mt7996_mcu_add_sta() issued the VoW DRR control commands for a station
before sending the STA_REC that instantiates it in the firmware. On a
fresh peer entry there is no station context yet, so the firmware
rejects UNI_VOW_DRR_CTRL with 0xC0000001, logging "GetDisablePerStaTx
Failed". That error was returned to the caller, which freed the STA_REC
skb without ever sending it, so bringing up client mode occasionally
failed with "failed to move station to desired state".

Send the STA_REC first and set up the airtime scheduler afterwards.
Airtime fairness is not required for the link to work and the station
record has already been committed at that point, so a failure there no
longer aborts the connection.
