[PATCH mt76 3/5] wifi: mt76: mt7996: take over connection monitoring

mt76 runs its own beacon monitor. mt76_beacon_mon_check() counts a miss
for each affiliated link of an MLD, and it stops the count while the phy
is off channel. mt7996 supplies it through mt76_rx_beacon(), but it does
not set CONNECTION_MONITOR. Therefore mac80211 also starts its legacy
monitor.

The legacy monitor knows one interface, not a set of links. It also
counts while the radio serves a different link. After seven beacon
intervals it removes an association that still carries traffic on the
other links.

Set the CONNECTION_MONITOR flag to disable the legacy monitor.
