Avoid network selection from scan during connection

If scan results arrive during the connection process, the network
selection function was called, interrupting the current connection.
While a regular scan is mutually exclusive with connection establishment
via the nature of radio work, there's no such protection for scheduled
scan. Prevent network selection while a connection is in progress.
