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.
