IMPALA-5940: Avoid stack tracing and log spew with Status::Expected()

This change converts some callers of Status() to Status::Expected()
in the DataStreamMgr to avoid log spew and unnecessary overhead of
stack tracing.

We didn't feed this error code back to the sender in the non-krpc case yet. Don't think we do anything for IMPALA-3990 in the non-krpc case.

This is very unlikely to occur even under load. This is more likely due to a logical error in the code IMHO so I leave it as Status for now.

Not really as this doesn't provide much information. We need to propagate an error status to the sender to alleviate the issue described in IMPALA-3990.
