    Hyper-V: properly handle UNC instance paths

    If the configured instances dir is an UNC path such as
    \\ip\share\instances_dir, the HyperV driver fails to query the available
    disk size, as it expects a path containing a drive letter.

    Also, when attempting to move instance files during live migrations, it
    will incorrectly try to build the remote path.

    This change addresses those issues and is part of a bigger series,
    attempting to fix HyperV shared storage related issues.
