Include image block device maps in info

In cases for example soft/hard reboot, we were just getting volume and
snapshot block device maps. For block devices with a source type image,
Nova would fall back on a local disk location and fail.

This change allows us to include block devices with a source of an
image, so that we correctly get the right the location of the block
device.
