[SPARK-19512][SQL] codegen for compare structs fails
## What changes were proposed in this pull request?
Set currentVars to null in GenerateOrdering.genComparisons before genCode
is called. genCode ignores INPUT_ROW if currentVars is not null and in
genComparisons we want it to use INPUT_ROW.
## How was this patch tested?
Added test with 2 queries in WholeStageCodegenSuite
