There are two new peer capables have been added since sctp_diag was
introduced into SCTP. When dumping the peer capables, these two new
peer capables should also be included. To not break the old capables,
reconf_capable takes the old hostname_address bit, and intl_capable
uses the higher available bit in sctpi_peer_capable.
