[PATCH] netfilter: byte order issue in nf_ct_seqadj_set

[Phil Oester <kernel@linuxace.com>]

In commit 41d73ec053d2, sequence number adjustments were moved to a separate
file.  Unfortunately, a necessary ntohl call was removed when the call to 
adjust_tcp_sequence was collapsed into nf_ct_seqadj_set.  As reported by
Dawid Stawiarsk, this broke the FTP NAT helper.  Add back the byte order
conversions.

Fixes: 41d73ec053d2 ("netfilter: nf_conntrack: make sequence number adjustments usuable without NAT")
