virtio_net: Use xdp_return_frame to free xdp_frames on destroying vqs

Browse Source 
[ Upstream commit 07b344f494 ]

put_page() can work as a fallback for freeing xdp_frames, but the
appropriate way is to use xdp_return_frame().

Fixes: cac320c850 ("virtio_net: convert to use generic xdp_frame and xdp_return_frame API")
