The QEMU NVMe simulator uses the intel vendor, qemu device id, and the first vendor specific byte to identify a lightnvm compatible nvme instance. Instead of using the Intel NVMe QEMU instance vendor and device id, let's use a preallocated from CNEX Labs instead. This lets us uniquely identify a QEMU lightnvm device without breaking other vendor specific work in the qemu device driver.
