BUG/MINOR: hlua: missing lock in hlua_filter_new()

Browse Source 
This is a complementary patch to 8670db7 ("BUG/MAJOR: hlua: improper lock
usage with hlua_ctx_resume()") for hlua_filter_new().

Indeed, the HLUA_E_ERRMSG case still relies on the lua stack but didn't
take the lock to do so.

This should be backported up to 2.6.
