net: hns3: remove unnecessary variable in hclge_get_mac_vlan_cmd_status()

The local variable return_status in hclge_get_mac_val_cmd_status()
is useless. So this patch returns the error code directly, instead of
using this variable. Also, replace some '%d' with '%u' in
hclge_get_mac_val_cmd_status().
