    vfio-user: avoid leaking duplicate device name

    vfio_user_pci_realize() assigns vbasedev->name before connecting to the
    server, then assigns the same name again after installing the request
    handler.  The second assignment overwrites the first allocation, so only
    the second string can be freed later by vfio_device_free_name().

    Drop the duplicate assignment and keep the first name allocation, which is
    also available on connection failures for error reporting.
