[SPARK-20492][SQL] Do not print empty parentheses for invalid primitive
types in parser
## What changes were proposed in this pull request?
Currently, when the type string is invalid, it looks printing empty
parentheses. This PR proposes a small improvement in an error message by
removing it in the parse as below:
```scala
spark.range(1).select($"col".cast("aa"))
```
**Before**
```
org.apache.spark.sql.catalyst.parser.ParseException:
DataType aa() is not supported.(line 1, pos 0)
== SQL ==
aa
^^^
```
**After**
```
org.apache.spark.sql.catalyst.parser.ParseException:
DataType aa is not supported.(line 1, pos 0)
== SQL ==
aa
^^^
```
## How was this patch tested?
Unit tests in `DataTypeParserSuite`.
