[libvirt] [PATCH v4 3/4] virStorageFileDeinit: don't free metadata used for storage driver access

[Prasanna Kumar Kalever]

Let the metadata for storage driver access to remote and local volumes
be cleaned by its respective driver *Deinit methods.

This will be used in the next patch, which will implement a connection
cache for/in gluster protocol driver.
