blk-cgroup: always terminate io.stat lines
With the removal of seq_get_buf in blkcg_print_one_stat, we cannot make adding the newline conditional on there being relevant stats because the name was already written out unconditionally. Otherwise we may end up with multiple device names in one line which is confusing and doesn't follow the nested-keyed file format.
