Subject: Fix network reload when config is restored

With scan mode opted in, supplicant connection is not shut
down even when wifi is turned off. This is a problem since
networks need to be reloaded when wifi is turned off and turned on
and this currently happens only on a supplicant connection.

Fix to handle this for scan mode state.
