bonding: Fix netconsole to not deadlock on rmmod
Netconsole calls netpoll_cleanup on receipt of a NETDEVICE_UNREGISTER event.
The notifier subsystem calls these event handlers with rtnl_lock held, which
netpoll_cleanup also takes, resulting in deadlock. Fix this by calling the
__netpoll_cleanup interior function instead, and fixing up the additional
pointers.
