Auto merge of #39799 - dpc:create_dir_all, r=alexcrichton

Fix race condition in fs::create_dir_all

The code would crash if the directory was created after create_dir_all
checked whether the directory already existed.  This was contrary to
the documentation which claimed to create the directory if it doesn't
exist, implying (but not stating) that there would not be a failure
due to the directory existing.
