wifi: mt76: mt792x: do not advertise active monitor

Browse Source 
mt76_phy_init() sets NL80211_FEATURE_ACTIVE_MONITOR for every mt76 device,
but mt792x firmware does not honor it: entering active monitor mode stops
RX. Gate the feature behind a new per-phy no_active_monitor flag and set it
for mt792x.
