[PATCH 5/6] ntdll: IOCTL_DVD_READ_STRUCTURE accepts long input buffers

Apps that define their own DVD_READ_STRUCTURE (to avoid needing the ddk)
and forget to pack it end up with pad bytes on the end of that struct.
Windows accepts this without complaint, so relax the input buffer size check.

This helps one demo app I know of (dodo.c by Takuya Murata).
