Add per-namespace debugfs directory support under the subsystem debugfs directory. Each enabled namespace gets a ns<nsid>/ directory created during nvmet_ns_enable() and removed during nvmet_ns_disable(). This provides the infrastructure for exposing namespace-specific debug information in subsequent patches.
