[SPARK-8658][SQL][FOLLOW-UP] AttributeReference's equals method compares all the members 

Based on the comment of cloud-fan in https://github.com/apache/spark/pull/9216, update the AttributeReference's hashCode function by including the hashCode of the other attributes including name, nullable and qualifiers.

Here, I am not 100% sure if we should include name in the hashCode calculation, since the original hashCode calculation does not include it.

marmbrus cloud-fan Please review if the changes are good.

Closes #9761 from gatorsmile/hashCodeNamedExpression.
