Raphael S. Carvalho 40e75fb109 streaming/stream_transfer_task: avoid pointless iterations in has_relevant_range_on_this_shard() ...

When has_relevant_range_on_this_shard() found a relevant range, it will unnecessarily
iterate through the end. Verified manually that this could be thousands of pointless
iterations when streaming data to a node just added. The relevant code could be
simplified by de-futurizing it but I think it remains so to allow task scheduler
to preempt it if necessary.
