Now in as 842bf64122

The swab filter should probably also consider a .block_size; there, we
can still support unaligned reads, but due to the overhead of byte
swapping, we want to ensure preferred size is at least our swap
alignment (but then again, the NBD spec says a preferred size has to
be at least 512, which is larger than our swap alignment.
