[PATCH net-next v5 7/8] veth: use napi_skb_cache_get_bulk() instead of xdp_alloc_skb_bulk()

[Alexander Lobakin <aleksander.lobakin@xxxxxxxxx>]

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 uses NAPI and GRO, so this is both context-safe
and beneficial.
