NVMe: Handle bios that contain non-virtually contiguous addresses
NVMe scatterlists must be virtually contiguous, like almost all I/Os.
However, when the filesystem lays out files with a hole, it can be that
adjacent LBAs map to non-adjacent virtual addresses. Handle this by
submitting one NVMe command at a time for each virtually discontiguous
range.
