[SPARK-2571] Correctly report shuffle read metrics.
Currently, shuffle read metrics are incorrectly reported when stages have
multiple shuffle dependencies (they are set to be the metrics from just one of
the shuffle dependencies, rather than the accumulated metrics from all of the
shuffle dependencies). This fixes that problem, and should probably be
back-ported to the 0.9 branch.
Thanks @ryanra for discovering this problem!
