Use argument structure for nvme_set_features() and nvme_get_features()

Use an argument structure instead of passing all arguments one by one.
This allows for a future expansion of the argument list without having
to change the library ABI.
Also convert zns.c to use nvme_zns_report_zones() instead of calling
nvme_zns_mgmt_recv() directly.
