[PATCH v2] win32: explicitly set errno to enoent if err is not error_directory

["Rose via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Seija Kijin <doremylover123@xxxxxxxxx>

At this point, the only two possible errors are
ERROR_DIRECTORY or ERROR_BAD_PATHNAME.

This code clarifies this and also saves a call to
err_win_to_posix.
