When IEEE80211_HW_CONNECTION_MONITOR is configured by the driver, starting of ieee80211_sta_conn_mon_timer should be prevented, as it is then not needed. This is currently partially the case. As it seems, when a probe-response is received from the AP the timer is still restarted, thus restarting the host based connection keep-alive mechanism. These probe-responses happen at least when scanning while associated. Fix this by preventing starting of the ieee80211_sta_conn_mon_timer in the ieee80211_rx_mgmt_probe_resp function.
