virtio-blk: Respect discard granularity
Report the configured granularity for discard operation to the
guest. If this is not set use the block size.
Since until now we have ignored the configured discard granularity
and always reported the block size, let's add
'report-discard-granularity' property and disable it for older
machine types to avoid migration issues.
