Fix sibling scan results update criteria for different channels

Fix sibling scan results update criteria for different channels

When scan results are received for a wpa_s instance, currently, other
wpa_s instances sharing the radio (siblings) will get updated with the
same scan results to reduce scan time.

But if the scan frequencies included in the requests for these siblings
are different, especially when they are exclusive when one wpa_s is a
non-AP MLD with 2.4 GHz and 5 GHz links and another wpa_s is a single
link non-AP MLD with 6 GHz link, the siblings will lose scan results for
the desired frequencies. Fix the sibling scan results update by checking
that they scan the same frequencies and they are not MANUAL_SCAN.
