[PATCH] block/nvme: Do not allow image creation with NVMe block driver

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

The NVMe driver does not support image creation.
The full drive has to be passed to the guest.

Before:

  $ qemu-img create -f raw nvme://0000:04:00.0/1 20G
  Formatting 'nvme://0000:04:00.0/1', fmt=raw size=21474836480

  $ qemu-img info nvme://0000:04:00.0/1
  image: nvme://0000:04:00.0/1
  file format: raw
  virtual size: 349 GiB (375083606016 bytes)
  disk size: unavailable

After:

  $ qemu-img create -f raw nvme://0000:04:00.0/1 20G
  qemu-img: nvme://0000:04:00.0/1: Protocol driver 'nvme' does not support image creation

Fixes: 5a5e7f8cd86 ("block: trickle down the fallback image creation function use to the block drivers")
