btrfs: Add check to avoid cleanup roots already in fs_info->dead_roots. Current btrfs_orphan_cleanup will also cleanup roots which is already in fs_info->dead_roots without protection. This will have conditional race with fs_info->cleaner_kthread. This patch will use refs in root->root_item to detect roots in dead_roots and avoid conflicts.
