sched: rt: fix SMP bandwidth balancing for throttled groups

Now we exceed the runtime and get throttled - the period rollover tick
will subtract the cpu quota from the runtime and check if we're below
quota. However with this cpu having a very small portion of the runtime
it will not refresh as fast as it should.

Therefore, also rebalance the runtime when we're throttled.
