This patch fixes the crash when registering the hashlimit extension
with xtables during init_extensions(when built with static libs) .
The option validation function xtables_option_metavalidate has a
loop termination condition of the entry name being NULL. The loop
does not terminate when validating hashlimit_mt_opts_v2 which causes
a crash on derefencing an invalid entry.
