net: hns3: modify the return code of hclge_get_ring_chain_from_mbx
Currently, function hclge_get_ring_chain_from_mbx will return -ENOMEM if ring_num is bigger than HCLGE_MBX_MAX_RING_CHAIN_PARAM_NUM. It is better to return -EINVAL for the invalid parameter case. So this patch fixes it by return -EINVAL in this abnormal branch.
