sctp: hold transport instead of assoc in sctp_diag
In sctp_transport_lookup_process(), Commit 1cceda784980 ("sctp: fix
the issue sctp_diag uses lock_sock in rcu_read_lock") moved cb() out
of rcu lock, but it put transport and hold assoc instead, and ignore
that cb() still uses transport. It may cause a use-after-free issue.
This patch is to hold transport instead of assoc there.
