Subject: [RFC v2 0/3] nvme: add csi, ms and nuse to sysfs

I've moved all ns id info to nvms_ns_head in this version as we discussed in v1
(hope I understood it right). The change was pretty much straightforward except for 

  nvme_mpath_clear_current_path
  nvme_mpath_revalidate_paths
  nvme_failover_req

where there is need to access a nvme_ns pointer again. I've tested this change
with the nvme-pci and nvme-tcp transport so far.

Thanks,
Daniel
