IMPALA-5586: Null-aware anti-join can take a long time to cancel

Queries with a null-aware anti-join joining on a large number of NULLs
can take a long time to cancel if threads are stuck in
PartitionedHashJoinNode::EvaluateNullProbe(). This change adds the
RETURN_IF_CANCELLED macro to the function.

Testing:
Added logs to PartitionedHashJoinNode::EvaluateNullProbe and made sure
that the function returns right away on cancellation.
