[PATCH 04/18] nvme: add a vendor field to struct nvme_dev

[Christoph Hellwig]

The SCSI translation layer currently has to poke into the PCI device
structure to find a vendor ID for the device identification fallback.
We won't nessecarily have a PCI device behind the device structure in
the future, so add a new vendor field that can be filled out by the
PCIe driver instead.
