virtio-net: drop NETIF_F_FRAGLIST
virtio declares support for NETIF_F_FRAGLIST, but assumes
that there are at most MAX_SKB_FRAGS + 2 fragments which isn't
always true with a fraglist.
A longer fraglist in the skb will make the call to skb_to_sgvec overflow
the sg array, leading to memory corruption.
Drop NETIF_F_FRAGLIST so we only get what we can handle.
