netfilter: Use correct return for seq_show functions
Using seq_has_overflowed doesn't produce the right return value.
Either 0 or -1 is, but 0 is much more common and works well when
seq allocation retries.
I believe this doesn't matter as the initial allocation is always
sufficient, this is just a correctness patch.
Miscellanea:
o Don't use strlen, use *ptr to determine if a string
should be emitted like all the other tests here
o Delete unnecessary return statements
