nvme/025: use character device for nvme effects-log command

The recent nvme-cli commit aec85d96e07f ("nvme: add error message for
mmap_registers") in the version v2.12 dropped the feature for "nvme
effects-log" command to fallback target devices from namespace block
devices to admin character devices. This made the test case nvme/025
fail with the message "Block device isn't allowed without csi". To avoid
the failure, use admin character devices instead of namespace block
devices.
