Use DEV_BSIZE byte sectors instead of PAGE_SIZE byte sectors for
swap-backed memory disks. This reduces filesystem allocation overhead
and makes swap-backed memory disks compatible with broken code (dd,
for example) which expects to see 512 byte sectors. The size of a
swap-backed memory disk must still be a multiple of the page size.
When performing page-aligned operations, this change has zero
performance impact.
