Document the dscheck(9) function and explain how it affects the slice-
and driver-relative block numbers, bio->bio_blkno and bio->bio_pblkno
respectively.

The latter is modified by the said function after doing various checks
on available information, such as disklabels, etc, while the former is
provided by the VFS.

Explain how said function re-transforms the block number fields when
LABEL support is enabled in the VN driver via vnconfig(8).
