    xen/passthrough: Render domains with %pd in the 'Q' debug handler
    
    IOMMUs are owned by DOM_XEN, and with XSA-302, DOM_IO is used for
    quarantined devices.  Use %pd in the printk to render the system
    domains more intelligently.
    
    Before:
      (XEN) 0000:00:01.0 - dom 0   - node 0   - MSIs < >
