Initialize the si_bsize fields of the new dev structure. This fixes
some swapper problems analogous to those experienced with ccd. This fix is a kludge: since we currently don't track the "sector size" in a volume label, we guess a worst case (4 kB, as used by vnode devices). If the concept of sector size is here to stay, I'll make some changes to track the "sector size" of a volume. This will probably be the maximum of the sector sizes of all component drives, but things could get ugly if we start allowing non-standard sector sizes such as 524 bytes.
