(btrfs-progs-v5.2) btrfs balance status /path --> starts balance, instead of reporting status

Hi, (I'm not subscribed).

In btrfs-progs-v5.2 (and -v5.1.1, don't know about older versions), when there is already balancing operation, then
btrfs balance status /path
reports its status. (OK)

But, there is no balancing operation, then it starts the balancing, instead of reporting some "status". (BUG)
