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

[Chaitanya Kulkarni <kch@nvidia.com>]

Similar to previous patch handle identify command cns value
NVME_ID_CNS_CS_CTRL when executing nvme_admin_identify for discovery
controller.

This is needed to mask out the errors reported by the blktest nvme/002.
