Although virtio-scsi supports SCSI PR, the device on host may do not
support it. To avoid losing data, we only allow one scsi hostdev to
be passthroughed to one live guest, Just like what we do for PCI
and USB devices.

v2.5 - v3:
   * Small changes, mainly on errors & coding style
I think this restriction should be limited to devices that do not have a
<shareable/> element, similar to disks.  I created BZ957292 for this.
Right, I should  use PATCH 0/n in the cover letter to indicate there
are still patches left..  They are in hand, but not good tested. Will
send them later & took the bug.

By the way, is there other -drive property which is nice to have for
scsi-generic?  Except the readonly.. (discard, serial, werror/rerror,
and cache, I don't see other useful properties for scsi-generic)?
