[PATCH net v2] selftests: netfilter: conntrack_dump_flush: remove unused variables and fix typo

[Qingshuang Fu]

From: Qingshuang Fu <fuqingshuang@kylinos.cn>

Remove unused 'rplnlh' in conntrack_data_insert(), and remove unused
'rplnlh' and 'nest' variables in conntrack_count_zone() and
conntrack_flush_zone(). These variables were declared but never used
since their introduction.

Also fix typo: rename misspelled conntracK_count_zone() to
conntrack_count_zone().

v2:
  - Drop Fixes tag as this is a cleanup, not a bug fix
  - Add Reviewed-by tag from Fernando Fernandez Mancera
  - Also fix the typo in function name conntracK_count_zone
  - Link to v1: https://lore.kernel.org/all/20260806075052.1934904-1-fffsqian@163.com/

If not a bug fix, you should target to net-next.

We will handle this though the nf-next tree.

Thanks.
