====================
netpoll: make sure napi_list is safe for RCU traversal

This series is a follow-up to the fix in commit 96e97bc07e ("net:
disable netpoll on fresh napis"). To avoid any latent race conditions
convert dev->napi_list to a proper RCU list. We need minor restructuring
because it looks like netif_napi_del() used to be idempotent, and
it may be quite hard to track down everyone who depends on that.
