Merge branch 'sctp-info-dump'

Xin Long says:

====================
sctp: add some missing peer_capables in sctp info dump

The 1st patch removes the unused and obsolete hostname_address from
sctp_association peer and also the bit from sctp_info peer_capables,
and then reuses its bit for reconf_capable and use the higher
available bit for intl_capable in the 2nd patch.
