Subject: [PATCH 1/7] netpoll: Set npinfo to NULL even with ndo_netpoll_cleanup

netpoll: Set npinfo to NULL even with ndo_netpoll_cleanup

Sinec we have to null npinfo regardless of whether there is a
ndo_netpoll_cleanup, it makes sense to do this unconditionally
in netpoll_cleanup rather than having every driver do it by
themselves.
