[PATCH 3/8] wpa_supplicant: Avoid net-select from scan during connection

[Ilan Peer]

From: Arik Nemtsov <arik at wizery.com>

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