net: hns3: fix GRE checksum offload issue

mainline inclusion
from mainline-v6.6-rc3
commit f9f65126
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I83ZCY
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f9f651261130cdcb7adc9a3e365b356bc2749ab3



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

The device_version V3 hardware can't offload the checksum for IP in GRE
packets, but can do it for NvGRE. So default to disable the checksum and
GSO offload for GRE, but keep the ability to enable it when only using
NvGRE.
