virtio-net: fix for skb_over_panic inside big mode
commit 126285651b7f ("Merge ra.kernel.org:/pub/scm/linux/kernel/git/netdev/net")
accidentally reverted the effect of
commit 1a8024239da ("virtio-net: fix for skb_over_panic inside big mode")
on drivers/net/virtio_net.c
As a result, users of crosvm (which is using large packet mode)
are experiencing crashes with 5.14-rc1 and above that do not
occur with 5.13.
