wifi: rtw89: mcc: reset probe counter when receiving beacon
[ Upstream commit 1b40c1c7571fcf926095ed92f25bd87900bdc8ed ]
For BE chips, needs to transmit QoS null data periodically to ensure
the connection with AP in GC+STA mode. However, in environments
with interference, the Qos null data might fail to transmit
successfully. Therefore, when receive the beacon from AP will
reset the QoS null data failure counter to avoid unnecessary
disconnection.
