  Only one NVMe device is usable in Windows (10) guest

Status in QEMU:

Bug description:
  Full command: qemu-system-x86_64 -enable-kvm -cpu host -smp cores=4 -m
  4G -net bridge -net nic -full-screen -drive
  file=ovmf_x64.bin,format=raw,if=pflash -drive
  file=disks/win16_ide.img,format=raw,cache=none,aio=native -drive
  file=disks/one.img,if=none,format=qcow2,id=one -drive
  file=disks/two.img,if=none,format=qcow2,id=two -device
  nvme,drive=one,serial=E86C3CFC43518D6F -device

  QEMU version: 2.5.0

  Kernel: 4.5.1 (Arch Linux)

  When there are two NVMe devices specified, only the second one will be
  usable in Windows. The following error is shown under "Device status"
  of the failed NVMe controller in Device Manager:

  "This device cannot start. (Code 10)

  The I/O device is configured incorrectly or the configuration
  parameters to the driver are incorrect."

  The only thing seems suspicious to me is that the nvme emulation in
  qemu does not have WWN/EUI-64 set for the devices, though I have no
  idea at all whether that is mandatory:

  "C:\Windows\system32>sg_vpd -i PD1
  Device Identification VPD page:
    Addressed logical unit:
      designator type: SCSI name string,  code set: UTF-8
        SCSI name string:

  C:\Windows\system32>sg_vpd -p sn PD1
