netfilter: x_tables: kill check_entry helper
Once we add more sanity testing to xt_check_entry_offsets it becomes relvant if we're expecting a 32bit 'config_compat' blob or a normal one. Since we already have a lot of similar-named functions (check_entry, compat_check_entry, find_and_check_entry, etc.) and the current incarnation is short just fold its contents into the callers.
