netfilter: x_tables: add and use xt_check_proc_name
commit b1d0a5d0cba4597c0394997b2d5fced3e3841b4e upstream.
recent and hashlimit both create /proc files, but only check that
name is 0 terminated.
This can trigger WARN() from procfs when name is "" or "/".
Add helper for this and then use it for both.
