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. Signed-off-by: Vanya Sergeev <vsergeev@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
