[PATCH bpf-next 8/9] veth: use napi_skb_cache_get_bulk() instead of xdp_alloc_skb_bulk()

[Alexander Lobakin]

Now that we can bulk-allocate skbs from the NAPI cache, use that
function to do that in veth as well instead of direct allocation from
the kmem caches. veth already uses NAPI for Rx processing, so this is
safe from the context perspective. veth also uses GRO, so using NAPI
caches makes real difference here.
