net: hns3: refactor VF tqp stats APIs with new common tqp stats APIs

mainline inclusion
from mainline-master
commit 4afc310c
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4Q02P
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4afc310cf9a8

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

This patch firstly uses new tqp struct(hclge_comm_tqp) and removes the
old VF tqp struct(hclgevf_tqp). All the tqp stats members used in VF module
are modified according to the new hclge_comm_tqp.

Secondly VF tqp stats APIs are refactored to use new common tqp stats APIs.
The old tqp stats APIs in VF are deleted.
