When wpa_supplicant is initiated by users and not by NetworkManager,
the CQM configuration might not be set. Without this setting, ICs
with connection monitor handled by driver won't detect connection
loss. To fix this we prepare a default setting upon associated at
first, then update again if any is given later.
