[PATCH] selftests: netfilter: Remove unused variables in conntrack_dump_flush

[Qingshuang Fu]

From: Qingshuang Fu <fuqingshu...@kylinos.cn>

The variables 'rplnlh' in conntrack_data_insert() and 'rplnlh' together
with 'nest' in conntracK_count_zone() and conntrack_flush_zone() were
declared but never used since they were introduced.

Similarly, commit 76342e842587 ("selftests: netfilter: remove unused
parameter") removed the unused 'err' variable from these functions but
overlooked the remaining unused 'rplnlh' and 'nest' variables.  Remove
them to clean up the code.

Fixes: eff3c558bb7e ("netfilter: ctnetlink: support filtering by zone")
