netfilter: nf_nat_helper: tidy up adjust_tcp_sequence
The variable 'other_way' gets initialized but is not read afterwards,
so remove it. Pass the right arguments to a pr_debug call.
While being at tidy up a bit and it fix this checkpatch warning:
WARNING: suspect code indent for conditional statements
