IB/mthca: Set cleaned CQEs back to HW ownership when cleaning CQ
mthca_cq_clean() updates the CQ consumer index without moving CQEs
back to HW ownership. As a result, the same WRID might get reported
twice, resulting in a use-after-free. This was observed in IPoIB CM.
Fix by moving all freed CQEs to HW ownership.
