inet: fix unsafe access to _res.options in res_mkquery()
res_mkquery() takes out __resolv_lock to copy _res.options to function local
_res_options on line 4204, but later unsafely accesses _res.options without a
lock, instead of its local copy _res_options, on line 4221. Looks like a
period / underscore typo.
