netpoll: Allow netpoll_setup/cleanup recursion
This patch adds the functions __netpoll_setup/__netpoll_cleanup which is designed to be called recursively through ndo_netpoll_seutp. They must be called with RTNL held, and the caller must initialise np->dev and ensure that it has a valid reference count.
