KVM creates debugfs files to export VM statistics to userland. To be able to remove them on kvm exit it tracks the files' dentries. Since their parent directory is also tracked and since each parent direntry knows its children we can easily remove them by using debugfs_remove_recursive(kvm_debugfs_dir). Therefore we don't need the extra tracking in the kvm_stats_debugfs_item anymore.
