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.

Fixes: bb7e7801704e ("net/mlx5: optimize mlx5 flow RSS struct")
