Tim Armstrong 7a0ee685b8 IMPALA-5446: dropped Sorter::Reset() status ...

This patch aligns the sorter's methods closer with the ExecNode methods
and moves the possibly-failing parts of Reset() into Open().

Testing:
Added WARN_UNUSED_RESULT to all the sorter methods that return Status to
prevent similar issues in future.

Add a test that sometimes goes down this code path. It was able to cause
a crash at least once every 5 executions.

Ran an exhaustive build to make sure there were no other regressions.
