Public bug reported:
Microsoft NTFS utilizes the FUA bit in SCSI WRITE CDBs to insure
integrity when a device advertises that it has write caching enabled.
The FUA bit is meant to ensure a write is written to non-volatile
storage before returning. This seems to not be enforced by QEMU's SCSI
emulation code.
