nvme: bump PCI revision

The broken Identify implementation in earlier Qemu versions means we
need to blacklist it from issueing the NVMe 1.1 Identify Namespace List
command.  As we want to be able to use it in newer Qemu versions we need
a way to identify those.  Bump the PCI revision as a guest visible
indicator of this bug fix.
