Xin Long 27af86bb03 sctp: do not pr_err for the duplicated node in transport rhlist ...

The pr_err in sctp_hash_transport was supposed to report a sctp bug
for using rhashtable/rhlist.

The err '-EEXIST' introduced in Commit cd2b708750 ("sctp: check
duplicate node before inserting a new transport") doesn't belong
to that case.

So just return -EEXIST back without pr_err any kmsg.

Fixes: cd2b708750 ("sctp: check duplicate node before inserting a new transport")
