The vendor specific designator in the Device Identification VPD page has
two problems:
1. It defaults to the BlockBackend name (-drive id=...), which everyone
expected to be a host detail that the guest never sees
2. With -blockdev based setups it defaults to an empty string; if this
default is used with more than one disk, the guest OS will interpret
this as a single multipath disk.
We can address problem 2 immediately, and start running the deprecation
clock for problem 1.

scsi-disk: Don't use empty string as device id
scsi-disk: Add device_id property
scsi-disk: Deprecate device_id fallback to BlockBackend name
