When we use get blockjob info to a unexist disk path, we will
get a error like this:
# virsh blockjob r7 vdc
error: An error occurred, but the cause is unknown
This is because we do not set the error when jump to endjob.
As virDomainDiskByName won't set the error, we need set them
in the callers function.

Since the 'path' parameter can be both path and a disk name (e.g. 'vdc' in your example), I wouldn't use "path" here because it looks weird when you get an error saying: invalid path vdc not assigned to domain I'd change it to something more abstract like: Disk '%s' not found in the domain or anything else but with such specification. If you're OK with that I'll push it with the modification (also fixing the commit message).
