Anatol Belski 6404d2d513 block: Assume sparse support for block devices ...

There is no non destructive readonly ioctl to query block device
discard or write zeroes capabilities. BLKZEROOUT is guaranteed to
succeed via kernel software fallback. BLKDISCARD may fail at runtime
with EOPNOTSUPP on devices that lack trim support, but the error
propagates to the guest as VIRTIO_BLK_S_IOERR and well behaved
guests handle it gracefully.
