net/hns3: remove QinQ insert support for VF
[ upstream commit f6e79b8d3968150736499bc225762b62fbf1b768 ] In the HIP08 platform, the PF driver will notify VF driver to update the PVID state [1], and VF will declare support QinQ insert when PVID is disabled. In the later platform (e.g. HIP09), the hardware has been improved, so the PF driver will NOT notify VF driver to update the PVID state. However, the later platform still have constraint: PVID and QinQ insert cannot be enabled at the same time, otherwise, the hardware discards packets and reports an error interrupt. Plus, as far as we known, VF driver's users don't use the QinQ insert. Therefore, we declare that the VF driver don't support QinQ insert.
