[GIT PULL] some more early nvme patches for kernel 4.13

[Sagi Grimberg]

Hey Jens,

Another round of early patches for 4.13 to spend some time
in linux-next.

This includes:
- finally remove SCSI translations from Kieth 
- NQN handling fixes from Christoph
- several nvme(t)-fc fixes from James
- expose hostid configure knob to userspace from Johannes
- APST disable quirks from Kai-Heng Feng
- nvme-pci process_cq refactoring from me
- relax NVME_AQ_DEPTH to 32 and share it in fabrics and pci from me
- fix nvmet-rdma surprise device removal handling

please consider pulling from:

  git://git.infradead.org/nvme.git nvme-4.13

It's rebased on top of your for-next (2c4a9e73b3c6).

Thanks!
