HOTFIX: poll with zero millis during restoration Mirror of #4096 for 0.11.01. During the restoration phase, when thread state is still in PARTITION_ASSIGNED not RUNNING yet, call poll() on the normal consumer with 0 millisecond timeout, to unblock the restoration of other tasks as soon as possible.
