net: hns3: fix wrong tc bandwidth weight data issue 

mainline inclusion
from mainline-v6.5-rc2
commit 116d9f73
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7OL9R
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=116d9f732eef634abbd871f2c6f613a5b4677742



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

Currently, the weight saved by the driver is used as the query result,
which may be different from the actual weight in the register.
Therefore, the register value read from the firmware is used
as the query result
