examples/nvme/identify: print ZNS data structures if supported

Browse Source 
Print the Zoned Namespace Command Set Specific data structures,
if the namespace/controller supports them.

spdk_nvme_zns_ctrlr_get_data() returns NULL for a controller
that does not support the ZNS specific controller data struct.
