vmd(8): correct comment in vioraw, cleanup formatting.

Comment incorrectly mentioned returning sectors when this function
returns bytes; the logic in virtio.c computes the number of 512
byte sectors after calling virtio_raw_init.

While here, adjust the formatting of return's to match the rest of vmd.

No functional change.
