Subject: [PATCH net-next] sctp: remove redundant null check on asoc

In sctp_err_lookup, goto out while the asoc is not NULL, so remove the
check NULL. Also, in sctp_err_finish which called by sctp_v4_err and
sctp_v6_err, they pass asoc to sctp_err_finish while the asoc is not
NULL, so remove the check.
