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.
