virtio/vhost: cross endian support

Ugh. Does this really have to be dynamic?

Can't virtio do the sane thing, and just use a _fixed_ endianness?

Doing a unconditional byte swap is faster and simpler than the crazy
conditionals. That's true regardless of endianness, but gets to be
even more so if the fixed endianness is little-endian, since BE is
not-so-slowly fading from the world.
