qcacmn: remove the QDF_BUG in src port learn when peer found

Remove the QDF_BUG in sa valid case when AST entry is not found
and peer is found as this can be a valid case in DBDC repeater

In DBDC repeater case we may receive the L2UF frame sent on 5G
radio on 2G interface

In this case SA will be valid and peer will be found for 5G VAP
mac address, but ast entry will not be found in ast_table as we
dont receive peer map events for STA vaps
