pci: strengthen requirement of the correct subsystem id
If a hardware implementation of virtio does not have
the correct subsystem id, then drivers can't report
ir properly, or detect and work around bugs.
Change the requirement from MAY to SHOULD.
We can't make it a MUST since we did not require this
historically.
