wpa_cli: Allow first DISCONNECTED event to be reported

wpa_cli filters out extra DISCONNECTED events from action scripts. This
ended up filtering out the first real DISCONNECT event in case wpa_cli
was started when wpa_supplicant was in connected state. Change wpa_cli
to allow the first disconnection event to be reported to the action
script in such case.
