[SPARK-19239][PySpark] Check the lowerBound and upperBound whether equals
None in jdbc API
## What changes were proposed in this pull request?
The `jdbc` API do not check the `lowerBound` and `upperBound` when we
specified the ``column``, and just throw the following exception:
>```int() argument must be a string or a number, not 'NoneType'```
If we check the parameter, we can give a more friendly suggestion.
## How was this patch tested?
Test using the pyspark shell, without the lowerBound and upperBound
parameters.
