qcacld-3.0: Add link entry to policy_mgr upon legacy to MLO roam

Currently, link entry is not added to connection_list of
policy_mgr in case of legacy to MLO roaming. This causes
policy_mgr to miss track of the MLO link.
Check if the connection entry is present in the policy mgr
for the link vdev id and add an entry if it's not present.
