LU-15018 o2iblnd: treat cmid->device == NULL as an error

LU-15018 o2iblnd: treat cmid->device == NULL as an error

Even if rdma_bind_addr is successful, kiblnd_dev_failover should
treat cmid->device == NULL as an error in order to later avoid
calling kiblnd_set_ni_fatal_on with possibly dev->ibd_hdev == NULL.

Test-Parameters: trivial
