The QEMU NVMe simulator uses the intel vendor, qemu device id, and the
first vendor specific byte to identify a lightnvm compatible nvme

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.
