qemuBuildStorageSourceChainAttachPrepareBlockdev prepares the full backing chain for attachment via blockdev. For snapshots we'll need to prepare one image only as it needs to be plugged on top of the existing chain. This patch introduces qemuBuildStorageSourceChainAttachPrepareBlockdevTop which prepares only @top similarly to the original function by splitting out the functionality into an internal function so that the API does not change.
