net: mvneta: rely on napi_build_skb() in mvneta_swbm_build_skb()

Browse Source 
mvneta_swbm_build_skb() is only invoked from mvneta_poll(), the NAPI
poll routine, so it always runs in NAPI context. Use napi_build_skb()
instead of build_skb() to source the skb head from the per-CPU NAPI
cache, avoiding a per-packet kmem_cache_alloc() of the skb head.
