[PATCH 3/9] netconsole: move refill_skbs_work_handler() from netpoll

[Breno Leitao <leitao@debian.org>]

The work handler is wired via INIT_WORK() in
netconsole_skb_pool_init() and has no other callers since the
previous patch took the skb pool lifecycle out of __netpoll_setup().
Move the function body into drivers/net/netconsole.c as a
file-static helper, drop EXPORT_SYMBOL_GPL() and remove the
prototype from <linux/netpoll.h>.

Pure code motion: the body is unchanged and still calls the
exported refill_skbs() in net/core/netpoll.c.
