net: hns3: fix invalid mutex between tc qdisc and dcb ets command issue

mainline inclusion
from mainline-v6.6-rc1
commit fa556494
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7YRUW
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=fa5564945f7d15ae2390b00c08b6abaef0165cda



----------------------------------------------------------------------

We hope that tc qdisc and dcb ets commands can not be used crosswise.
If we want to use any of the commands to configure tc,
We must use the other command to clear the existing configuration.

However, when we configure a single tc with tc qdisc,
we can still configure it with dcb ets.
Because we use mqprio_active as the tag of tc qdisc configuration,
but with dcb ets, we do not check mqprio_active.

This patch fix this issue by check mqprio_active before
executing the dcb ets command. and add dcb_ets_active to
replace HCLGE_FLAG_DCB_ENABLE and HCLGE_FLAG_MQPRIO_ENABLE
at the hclge layer,
