In the function rxe_create_cq, when rxe_cq_from_init fails, the function

rxe_cleanup will be called to handle the allocated resources. In fact,

some memory resources have already been freed in the function

rxe_cq_from_init. Thus, this problem will occur.

The solution is to let rxe_cleanup do all the work.
