virtio-blk: reject configs with logical block size > physical block size
virtio-blk logical block size should never be larger than physical block
size because it doesn't make sense to have such configurations. QEMU doesn't
have a way to effectively express this condition; the best it can do is
report the physical block exponent as 0 - indicating the logical block size
equals the physical block size.
This is identical to commit 3da023b5827543ee4c022986ea2ad9d1274410b2
but applied to virtio-blk (instead of virtio-scsi).
