OK, we'll work on another patch to do this. The plan will be:

When CONFIG_NVME_MULTIPATH=y, you get multipath.c and full support for both nvme multipath (CMIC/NMIC = 1) and non-multipath 
devices (CMIC/NMIC=0) devices with 1 /dev entry per namespace.

When CONFIG_NVME_MULTIPATH=n, you get support for non-multipath devices (CMIC/NMIC=0) devices, but multipath devices 
(CMIC/NMIC=1) will only expose the first controller/namespace path.
