netconsole: move skb_pool / refill_wq from struct netpoll to netconsole_target

Browse source

These two fields back the fallback skb pool that find_skb() uses.
Every helper that touches them lives in netconsole now (refill_skbs,
refill_skbs_work_handler, netconsole_skb_pool_init,
netconsole_skb_pool_flush, find_skb, netcons_skb_pop), so the data
can move alongside its only consumer.

Add skb_pool and refill_wq to struct netconsole_target, drop them
from struct netpoll.

This will save 48-bytes for every netpoll user instance (except
netconsole that will have it in netconsole target struct).
