wifi: cfg80211: reject unsupported PMSR FTM location requests

Browse Source 
PMSR FTM location request flags are syntactically valid, but they must
be rejected when the device capability does not advertise support for
them.

Return an error immediately after rejecting unsupported LCI or civic
location request bits so the request cannot reach the driver.
