fsck should use the same values in checking as newfs does in creating
a filesystem. fs_nspf and its derivitives like fs_spc are DEV_BSIZE
values, not actual hardware disk sector values. Adjust initializations
accordingly.
Tweak header and man page comments to make the DEV_BSIZE'ness more
obvious for future spelunkers.
No-op for DEV_BSIZE (a.k.a. 512-byte) sector devices but should help
checking filesystems on, e.g., 4k-byte sector devices.
ok jmc@ on the man page tweaks.
