nvmet: add passthru ZNS support
In the default passthru implementation NVMeOF target passthru ctrl is not capable of handling Zoned Namespaces (ZNS). Update the nvmet_parse_pasthru_admin_cmd() to allow NVME_ID_CNS_CS_CTRL/NVME_CIS_ZNS and NVME_ID_CNS_CS_NS/NVME_CIS_ZNS. With this addition NVMeOF Passthru allows Zoned Namespaces.
