The following commit introduced separate is_user members for struct rxe_sq/rxe_rq/rxe_srq but no code uses the separate is_user member of struct rxe_sq and lots of code still use the common is_user member of struct rxe_qp. So it is clear to make all code use separate is_user members uniformly and remove the common is_user member.
