qcacmn: Don't allow SLO candidate for specified AP

When MLO STA connects to a specified buggy MLO AP with PMKID in assoc
req, it consistently fails and then retries with a downgraded SLO
candidate, which eventually succeeds. However, the customer expects MLMR
connection.

To address this, when select this buggy AP, we avoid generating
downgraded SLO/11AX candidates, use full SAE auth instead of existed PMKSA,
and don't add PMKID in RSNIEof assoc req when connect.
