The appropriate units for disk block addresses are always DEV_BSIZE, even when the underlying device has a larger sector size. Therefore, the filesystem code should not (and with this patch does not) try to use the underlying sector size when doing disk block address calculations.

This patch fixes problems in -current when using the swap-based
memory-disk device (mdconfig -a -t swap ...). This bugfix is not
relevant to -stable as -stable does not have the memory-disk device.
