[PATCH 1/2] nvmet: handle admin default command set identifier

[Chaitanya Kulkarni <kch@nvidia.com>]

The NVMeOF in kernel host when configuring non-mdts limits uses
idnetify controller cns value to NVME_ID_CNS_CS_CTRL and csi value to
NVME_CSI_NVM. In target code we only handle case for NVME_ID_CNS_CS_CTRL
and NVME_CSI_ZNS when CONFIG_BLK_DEV_ZONED is set.

Handle missing case for CONFIG_BLK_DEV_ZONED and !CONFIG_BLK_DEV_ZONED
so it can handle NVME_ID_CNS_CS_CTRL with NVME_CSI_NVM.

This is needed to mask out the errors reported by the blktest nvme/012.
