Skip the hardware dbuf slice update if we don't have active
pipes. With no active pipes, we don't have powerwell and thus
programming the dbuf slice counts leads to accessing
hardware without runtime pm ref.

Skip the hardware dbuf slice update if we don't have active
pipes. With no active pipes, we don't have powerwell and thus
programming the dbuf slice counts leads to accessing
hardware without runtime pm ref.
