qcacld-3.0: Process disconnect even if peer is not present

When DUT roams from one set of links(e.g. 2 GHz + 5 GHz) to
another set of links(e.g. 5 GHz + 6 GHz) in the same AP, there
might be a common link/peer(e.g. 5 GHz link). Current MLO roaming
design doesn't allow the common link peer creation as it's
already present on another link in previous connection.
Added changes to cleanup all peers as part of roam sync
processing on first vdev if it's a self ML roaming.
So, peers get deleted at the beginning itself and if roam sync
fails due to any reason, no new peer gets created.
Next HO_FAIL/disconnection should go through though peer
is not present.
Add changes for the same.
