ETS class reconfiguration can change a class quantum while the class
remains active.  The scheduler keeps the old deficit and spends that
stale credit under the new configuration.

This can be observed by making a class active, changing its quantum, and
then dequeuing with the old deficit still present.

When an active class quantum changes, reseed its deficit from the new
quantum so the new class parameters take effect immediately.
