net: hns3: refactor VF rss get APIs with new common rss get APIs

mainline inclusion
from mainline-master
commit 027733b1
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=027733b12a10

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

This patch firstly uses new rss parameter struct(hclge_comm_rss_cfg) as
child member of hclgevf_dev and deletes the original child rss parameter
member(hclgevf_rss_cfg). All the rss parameter members used in VF rss
module is modified according to the new hclge_comm_rss_cfg.

Secondly VF rss get APIs are refactored to use new common rss get APIs. The
old rss get APIs in VF are deleted.
