[Qemu-devel] [PATCH for-2.3] hmp: fix crash in 'info block -n -v' |

The image field in BlockDeviceInfo should never be null, however
bdrv_block_device_info() is not filling it in.
This makes the 'info block -n -v' command crash QEMU.
The proper solution is probably to move the relevant code from
bdrv_query_info() to bdrv_block_device_info(), but since we're too
close to the release for that this simpler workaround solves the
crash.
