Currently, RSS description data is saved in the mlx5 private data. It dose not support the nest flow_list_create() routine.
In the case with mark reg copy, the flow_list_create() function will be called nested. The RSS description data will be cleared in the nested case. Allocate one more RSS description to avoid the nested case.
