Fix unintentional reconnection on disconnect request

Fix unintentional reconnection on disconnect request

If the connection is canceled due to a disconnect request
during a connection attempt, depending on the connection progress,
it may be judged as a connection failure and reconnection may be attempted
with another BSSID within the same SSID group.
However, if a disconnect request is received, reconnection should not be attempted,
so the related code has been modified to skip it.
