When the "No host device provided" error occurs, the hint message
that starts with "Use -vfio-pci," makes no sense, since "-vfio-pci"
is not a valid command line parameter.

Correct this by replacing "-vfio-pci" with "-device vfio-pci".

Hey Alex,

Please ignore the "RFC" tag in the subject. Sorry for the mistake.
