Restart sched_scan on channel list change

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 needs to be reconfigured
accordingly for the scheduled scan.

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