s3: Fix shadow copy display on Windows 7

Windows 7 is a bit more picky on our NT_STATUS_BUFFER_TOO_SMALL. Announce the
right buffer size, the same amount we later check for.

Fix bug #6850 (Shadow Copy Support for VISTA / Windows 7).
(cherry picked from commit dc3d1f2f073f135bf48a08163010465ba88b9d37)
