[SPARK-5498][SQL]fix query exception when partition schema does not match table schema

In hive,the schema of partition may be difference from  the table schema.When we use spark-sql to query the data of partition which schema is difference from the table schema,we will get the exceptions as the description of the [jira](https://issues.apache.org/jira/browse/SPARK-5498) .For example:
* We take a look of the schema for the partition and the table

```sql
DESCRIBE partition_test PARTITION (dt='1');
id                  	int              	None
name                	string              	None
dt                  	string              	None

# Partition Information
# col_name            	data_type           	comment

dt                  	string              	None
```
```
DESCRIBE partition_test;
OK
id                  	bigint              	None
name                	string              	None
dt                  	string              	None

# Partition Information
# col_name            	data_type           	comment

dt                  	string              	None
```
*  run the sql
```sql
SELECT * FROM partition_test where dt='1';
```
we will get the cast exception `java.lang.ClassCastException: org.apache.spark.sql.catalyst.expressions.MutableLong cannot be cast to org.apache.spark.sql.catalyst.expressions.MutableInt`
