losetup.8: Clarify --direct-io

See e.g. containers/bootc#375 (comment) The phrasing here was in my opinion technically correct but quite confusing and easy to misunderstand. Let's be very clear: - The default is *off* - You can turn it on in two ways - You can also explicitly turn it off Signed-off-by: Colin Walters <walters@verbum.org>
