RDMA/rxe: Set wqe->status correctly if an unexpected response is received

commit 61b717d041b1976530f68f8b539b2e3a7dd8e39c upstream.

Every function that returns COMPST_ERROR must set wqe->status to another
value than IB_WC_SUCCESS before returning COMPST_ERROR. Fix the only code
path for which this is not yet the case.
