wifi: rtw88: Set default CQM config if not present

When wpa_supplicant is initiated by users and not by NetworkManager,
the CQM configuration might not be set. Without this setting, ICs
with connection quality monitor handled by firmware 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.
