Jason Wang ad9168674d virtio-net: correctly redirect linearized packet ...

[ Upstream commit 6890418bbb ]

After a linearized packet was redirected by XDP, we should not go for
the err path which will try to pop buffers for the next packet and
increase the drop counter. Fixing this by just drop the page refcnt
for the original page.
