For historical reasons the helpers [btrfs_]open_dir... return also the 'DIR *dirstream' value when a directory is opened. However this is never used. So avoid calling diropen() and return only the fd. Replace the last btrfs_open_dir() call with btrfs_open_dir_fd() removing any reference to the unused/useless dirstream variables. Also update the add_seen_fsid() function removing any reference to dir stream (again this is never used).
