net: hns3: fix for vport->bw_limit overflow problem

Browse Source 
[ Upstream commit 2566f10676ba996b745e138f54f3e2f974311692 ]

When setting vport->bw_limit to hdev->tm_info.pg_info[0].bw_limit
in hclge_tm_vport_tc_info_update, vport->bw_limit can be as big as
HCLGE_ETHER_MAX_RATE (100000), which can not fit into u16 (65535).

So this patch fixes it by using u32 for vport->bw_limit.
