Subject: netfilter 03/04: xt_hashlimit does a wrong SEQ_SKIP

commit 683a04cebc63819a36b1db19843bd17771f05b55

    netfilter: xt_hashlimit does a wrong SEQ_SKIP
    
    The function dl_seq_show() returns 1 (equal to SEQ_SKIP) in case
    a seq_printf() call return -1.  It should return -1.
    
    This SEQ_SKIP behavior brakes processing the proc file e.g. via a
    pipe or just through less.
