[libvirt] PATCH: Fix crash after deleting storage vol fails

[Daniel P. Berrange]

After a little debugging on IRC we discovered a problem in the deletion
of storage volumes. We were mistakenly calling virStorageVolFree(vol)
even if the delete call  failed. So the pool got left with a NULL storage
volume, and later use of that pool could crash on this.
