[PATCH 1/5] wpa_s: restart sched scan on channel list change

[Eliad Peller]

From: Victor Goldenshtein <victorg at ti.com>

The channel list can be changed as a result of arriving
beacon hints during normal scan or as a result of local
Reg-Domain change, some passive channels can become
active and shall be reconfigured accordingly for the
scheduled scan.

This fixes the connection to hidden SSIDs on 5Ghz band
during default Reg-Domain 00 (world roaming).
