net/mlx5e: Switch to using napi_build_skb()
Use napi_build_skb() which uses NAPI percpu caches to obtain
skbuff_head instead of inplace allocation.
napi_build_skb() calls napi_skb_cache_get(), which returns a cached
skb, or allocates a bulk of NAPI_SKB_CACHE_BULK (16) if cache is empty.
Performance test:
TCP single stream, single ring, single core, default MTU (1500B).
Before: 26.5 Gbits/sec
After: 30.1 Gbits/sec (+13.6%)
