Cloudbyte fix create_cloned_volume parent id
Cloudbyte fix create_cloned_volume parent id

The CloudByte driver is reading the parent's volume id from the
new volume's source_volid.  There are some cases when this isn't set.
The source volume object/dict is passed in, so just access the id
from there.
