Christoph Hellwig 52c050236e virtio-blk: fail unaligned requests 
Like all block drivers virtio-blk should not allow small than block size
granularity access.  But given that the protocol specifies a
byte unit length field we currently accept such requests, which cause
qemu to abort() in lower layers.  Add checks to the main read and
write handlers to catch them early.
