[PATCH 5/7] vfio/ccw: Use the 'Error **errp' argument of vfio_ccw_realize()

[Cédric Le Goater]

The local error variable is kept for vfio_ccw_register_irq_notifier()
because it is not considered as a failing condition. We will change
how error reporting is done in following changes.

Remove the error_propagate() call.
