rdma: clean up of qemu_rdma_cleanup()
- It can't be determined by RDMAContext::cm_id != NULL if the connection
is established or not.
- RDMAContext::cm_id is leaked and not destroyed because it is set to NULL
too early.
- RDMAContext::qp is created by rdma_create_qp() so that it should be destroyed
by rdma_destroy_qp(). not ibv_destroy_qp()
