[rfc | patch 3/6] netpoll: change poll_napi to take a net_device

[Jeff Moyer <jmoyer@redhat.com>]

(sorry for munging the subject of the prior two patches)

The poll_napi routine is not specific to a netpoll.  It really should be
able to be called with a struct net_device.  Changing the routine to take a
struct net_device makes it easier to support the bonding driver, since we
will be implementing a netpoll_poll_dev routine, that will not have a
struct netpoll associated with it.
