netfilter: x_tables: introduce and use xt_copy_counters_from_user
commit 63ecb81aadf1c823c85c70a2bfd1ec9df3341a72 upstream.
commit d7591f0c41ce3e67600a982bab6989ef0f07b3ce upstream
The three variants use same copy&pasted code, condense this into a
helper and use that.
Make sure info.name is 0-terminated.
