[ Upstream commit 19eb1123b4e9337fe20b1763fec528f837ec6568 ]
When enabling 4 TC after setting the bandwidth of VF, the bandwidth
of VF will resume to default value, because of the qset resources
changed in this case.
This patch fixes it by using a fixed VF's qset resources according to
HNAE3_MAX_TC macro.
Fixes: ee9e44248f52 ("net: hns3: add support for configuring bandwidth of VF on the host")
