I think we can remove this cast, although it's so trivial that it doesn't seem to have any real impact. A similar cast also exists for mj_JoinState in ExecMergeJoin().
(These values represent the state of the Join state machine for HashJoin and MergeJoin respectively, so I kind of wonder if it might be better to define them as enum rather than using int.)
