Fix 2763: Revert "storage_migrate: check if target storage supports content type"

This reverts commit 95015dbbf2.

parse_volname always gives 'images' and not 'rootdir'. In most
cases the volume name alone does not contain the needed information,
e.g. vm-123-disk-0 can be both a VM volume or a container volume.
