P2P: Do not skip call to p2p_scan_res_handled()

Even if p2p_scan_res_handler() returns 1 to indicate that scan result
iteration should be stopped, the p2p_scan_res_handled() needs to be
called to clear p2p_scan_running and to get a callback that will start
any operations that were delayed because of the running scan.
