virtio-net: correctly redirect linearized packet
virtio-net: correctly transmit XDP buff af
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.
Fixes: 186b3c998c50 ("virtio-net: support XDP_REDIRECT")

Presently, efi_runtime_services() silently switch %cr3 from swapper_pgd
