iwlwifi: mvm: don't allow sched scans without matches to be started [ Upstream commit 5e56276e7555b34550d51459a801ff75eca8b907 ] The firmware can perform a scheduled scan with not matchsets passed, but it can't send notification that results were found. Since the userspace then cannot know when we got new results and the firmware wouldn't trigger a wake in case we are sleeping, it's better not to allow scans without matchsets.
