Problems reported that if multiple peers have "remove-private-AS replace-AS" with each other and all are using private asns, the as-path gets hosed and continues to grow when a prefix is removed. This fix disallows removing and replacing the private asn if it matches the peer's ASN so that normal as-path loop prevention will operate correctly.
