Subject: net: hns3: don't config TM DWRR twice when set ETS
Patch-mainline: v5.15-rc1
Git-commit: 7f2f8cf6ef668c1c745e229023f98663f47aa702
References: bsc#1190336

The function hclge_tm_dwrr_cfg() will be called twice in function
hclge_ieee_setets() when map_changed is true, the calling flow is
hclge_ieee_setets()
    hclge_map_update()
    |   hclge_tm_schd_setup_hw()
    |       hclge_tm_dwrr_cfg()
    hclge_notify_init_up()
    hclge_tm_dwrr_cfg()

It is no need to call hclge_tm_dwrr_cfg() twice actually, so just
return after calling hclge_notify_init_up().
