sctp: fix some type cast warnings introduced by transport rhashtable
These warnings were found by running 'make C=2 M=net/sctp/'. They are introduced by not aware of Endian for the port when coding transport rhashtable patches. Fixes: 7fda702f9315 ("sctp: use new rhlist interface on sctp transport rhashtable") Reported-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.
