net: hns3: replace macro of max qset number with specification

mainline inclusion
from mainline-v5.12-rc1-dontuse
commit 3f094bd1
category: feature
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3f094bd11a3720d2a00e9b6dfc53f1ab25884a49

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

The max qset number is a fixed value now and it is defined by a macro.
In order to support other value in different kinds of device, it is
better to use specification queried from firmware to replace macro.
