We will need this function in near future so that we know what
/dev device corresponds to the SCSI device.

For a new hostdev type='scsi_host' we have a number of
required functions for managing, adding, and removing the
host device to/from guests. Provide the basic infrastructure
for these tasks.
The name "SCSIVHost" (and its variants) is chosen to avoid
conflicts with existing code named "SCSIHost" to refer to
a hostdev type='scsi' protcol='none'.
