[PATCH net] sctp: do not mark sk dumped when inet_sctp_diag_fill returns err

[Xin Long]

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().

Fixes: 8f840e47f190 ("sctp: add the sctp_diag.c file")
