sctp: do not pr_err for the duplicated node in transport rhlist
[ Upstream commit 27af86bb038d9c8b8066cd17854ddaf2ea92bce1 ]
The pr_err in sctp_hash_transport was supposed to report a sctp bug
for using rhashtable/rhlist.
The err '-EEXIST' introduced in Commit cd2b70875058 ("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: cd2b70875058 ("sctp: check duplicate node before inserting a new transport")
