sctp_diag would not actually dump out sk/asoc if inet_sctp_diag_fill
returns err, in which case it shouldn't mark sk dumped by setting
cb->args[3] as 1 in sctp_sock_dump().
Otherwise, it could cause some asocs to have no parent's sk dumped
in 'ss --sctp'.
So this patch is to not set cb->args[3] when inet_sctp_diag_fill()
returns err in sctp_sock_dump().
