Add AP SME device feature flag to advertise that the SA Query 
procedures
are handled in driver.

If this flag is advertised SA Query request or response frames from 
peers
are not reported to userspace. Thus userspace components shall skip SA
Query specific validations.

Ex: When AP started with Operating Channel Validation(OCV) support and
channel switch occurs, hostapd starts SA Query timer for OCV enabled
STAs. Hostapd sends deauth to the STAs which didn't send SA Query
request before timeout, Hostapd can skip such validations when this 
flag
advertised.

So how's that going to work with older hostapd? It'll be offloaded, and
then hostapd doesn't know, so it's still going to disconnect them?

So should be that hostapd also opts in to this driver behaviour?

yes, we have to update hostapd also with new implementation based on the
feature flag.

Also ... it _really_ would be good if there were upstream drivers with
these things ...

I fully agree. But unfortunately none of the upstream drivers 
implemented
OCV features within them.
