   ### What changes were proposed in this pull request?
   The pr aims to fix bug for createDataFrame from complex type schema.
   
   ### Why are the changes needed?
   When I code UT for `DataFrameNaFunctions`, I found:
   val schema = new StructType()
         .add("c1", new StructType()
           .add("c1-1", StringType)
           .add("c1-2", StringType))
   val data = Seq(Row(Row(null, "a2")), Row(Row("b1", "b2")), Row(null))
   val df = spark.createDataFrame(data.asJava, schema)
   df.show()
   
   Unable to work. The error message is as follows:

   ### Does this PR introduce _any_ user-facing change?
   No.
   
   ### How was this patch tested?
   Add new UT
   Pass GA.
