[SPARK-14618][ML][DOC] Updated RegressionEvaluator.metricName param doc
## What changes were proposed in this pull request?
In Spark 1.4, we negated some metrics from RegressionEvaluator since
CrossValidator always maximized metrics. This was fixed in 1.5, but the docs
were not updated. This PR updates the docs.
## How was this patch tested?
no tests
