[PATCH v3 4/6] virtio-net: expose virtio_net_supported_guest_offloads()

[Hawkins Jiawei]

To support restoring offloads state in vdpa, need to expose
the function virtio_net_supported_guest_offloads().
QEMU uses this function to get the guest supported offloads
and no needs to send the corresponding CVQ command if guest
enables all supported features.
