Florian Westphal 9aaaa409c5 netfilter: x_tables: add and use xt_check_proc_name 
commit b1d0a5d0cb 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.
