net: hns3: fix wrong bw weight of disabled tc issue

Browse source

[ Upstream commit 882481b1c5 ]

In dwrr mode, the default bandwidth weight of disabled tc is set to 0.
If the bandwidth weight is 0, the mode will change to sp.
Therefore, disabled tc default bandwidth weight need changed to 1,
and 0 is returned when query the bandwidth weight of disabled tc.
In addition, driver need stop configure bandwidth weight if tc is disabled.
