Subject: ice: switch to napi_build_skb()
Patch-mainline: v5.17-rc1
Git-commit: 5ce666315848a4cb44485d8cd2c5887998da6606
References: jsc#PED-376

napi_build_skb() reuses per-cpu NAPI skbuff_head cache in order
to save some cycles on freeing/allocating skbuff_heads on every
new Rx or completed Tx.
ice driver runs Tx completion polling cycle right before the Rx
one and uses napi_consume_skb() to feed the cache with skbuff_heads
of completed entries, so it's never empty and always warm at that
moment. Switch to the napi_build_skb() to relax mm pressure on
heavy Rx.
