iwlwifi: mvm: disable scheduled scan



The iwlwifi scheduled scan implementation doesn't adhere to the
userspace API correctly - the API assumes that any new incoming
'incompatible' request (like scan or remain-on-channel for this
driver) will just cancel the scheduled scan. Instead our driver
relies on userspace cancelling it, thus breaking existing wpa_s
versions.
