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

Applied with some minor changes (use enum ip_conntrack_dir instead
of int, use function name literally instead of "%s()" with __func__).
