Add a kernel log when the balance ends, either for cancel or completed

Missing S-O-B.

Wouldn't that repeat the same once again? There are status messages
printed already, when eg. balance is cancelled or paused.
No it won't. They are under if - else if- else. The __btrfs_balance()
returns ECANCELED for both paused and canceled so bifurcating them
here is useful.
Thanks, Anand
