This breaks multiple hwsim test cases for OWE since the expected BSS
entry is not available. While I think I understand what this is trying
to do, it is not really acceptable to break test cases, so I cannot
apply this as-is. At minimum, those test cases would need to be
modified, but I'm not really sure this is actually correct behavior
since BSSs with a hidden SSID have been added to the scan results in all
existing cases for years.

And this should likely be within #ifdef CONFIG_OWE even if that were to
compile successfully without such conditional check.
