Subject: [PATCH net] net: hns3: fix get wrong value of function hclge_get_dscp_prio()

As the argument struct hnae3_handle *h of function hclge_get_dscp_prio()
can be other client registered in hnae3 layer, we need to transform it
into hnae3_handle of local nic client to get right dscp settings for
other clients.

Fixes: dfea275e06c2 ("net: hns3: optimize converting dscp to priority process of hns3_nic_select_queue()")
