[SPARK-6145][SQL] fix ORDER BY on nested fields
Based on #4904 with style errors fixed.
`LogicalPlan#resolve` will not only produce `Attribute`, but also
"`GetField` chain".
So in `ResolveSortReferences`, after resolve the ordering expressions, we
should not just collect the `Attribute` results, but also `Attribute` at the
bottom of "`GetField` chain".
