1) post_one_send() always processes kernel's send queue.
2) rxe_poll_cq() always processes kernel's completion queue.

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.
