warn if the array lacks the "nonstring" attribute[1]. Mark the arrays
with __nonstring to and correctly identify the char array as "not a C

9324731b99 wifi: iwlwifi: mld: avoid selecting bad links 
Currently, we don't select a link that wasn't heared in the last 5
seconds.
But if the link started to suffer from missed beacons more recent than
that, we might select this link even we really shouldn't,
leading to a disconnection instead of a link switch.

Fix this by checking if a link was heared in the last MLO scan,
if not - don't include it in the link selection.
Since we do an MLO scan on missed beacons, we will not hear that link in
that scan, and won't select it.

f31d666f0b wifi: iwlwifi: mld: always do MLO scan before link selection 
According to the requirements, if the last scan isn't older than 20
seconds, we can use its results and do the link selection without
scanning before.
But this applies only when trying to get back to EMLSR, not if the link
has bad RSSI/missed beacons.
Since an MLO scan is cheap anyway, and results from 20 seconds before
are really old, always scan before links switching.

fd04fbee7f wifi: iwlwifi: mld: enable OMI bandwidth reduction on 6 GHz 
Due to the iwl_mld_get_chandef_from_chanctx() logic, even after
the OMI handshake to reduce bandwidth the driver wouldn't apply
that to the PHY context, since it always uses the normal, not
the reduced, configuration on 6 GHz (not strictly always, but
OMI will only apply if the original bandwidth is > 80 MHz.) Fix
this by making that selection contingent on AP mode. Refactor
the code a bit to also make it clearer why the min_def isn't
used in that case (for FILS.)

when starting to really operate it. This also requires the
