kunit_kzalloc() may return NULL, dereferencing it without NULL check may
lead to NULL dereference.
Add a NULL check for ies.

On 6 GHz (and also 5 GHz to some degree), only a specific set of center
frequencies should be used depending on the channel bandwidth. Verify
this is the case on 6 GHz. For 5 GHz, we are more accepting as there are
APs that got it wrong historically.

If we just want to determine the length of the fragmented
data, we basically need the same logic, and really we want
it to be _literally_ the same logic, so it cannot be out
of sync in any way.
Allow calling cfg80211_defragment_element() without an output
buffer, where it then just returns the required output size.
Also add this to the tests, just to exercise it, using the
pre-calculated length to really do the defragmentation, which
checks that this is sufficient.

Aloka originally suggested that puncturing should be part of
the chandef, so that it's treated correctly. At the time, I
disagreed and it ended up not part of the chandef, but I've
now realized that this was wrong. Even for clients, the RX,
and perhaps more importantly, CCA configuration needs to take
puncturing into account.
Move puncturing into the chandef, and adjust all the code
accordingly. Also add a few tests for puncturing in chandef
compatibility checking.

Simplify cfg80211_chandef_compatible() a bit by switching
c1 and c2 around so that c1 is always the narrower one
(once they're not identical or narrow/S1G). Then we can
just check the various primary channels and exit with the
wider one (c2), or NULL.
Also refactor the primary 40/80/160 function to not have
all the calculations hard-coded, and use a wrapper around
it to check primary 40/80/160 compatibility.
While at it, add some kunit tests for this functionality.
Also expose the new cfg80211_chandef_primary_freq() to
drivers, mac80211 will use it.

If the reporting AP is part of the same MLD, then an entry in the RNR is
required in order to discover it again from the BSS generated from the
per-STA profile in the Multi-Link Probe Response.
We need this because we do not have a direct concept of an MLD AP and
just do the lookup from one to the other on the fly if needed. As such,
we need to ensure that this lookup will work both ways.
