[PATCH net-next-2.6] bonding: enable netpoll without checking link status

[Andy Gospodarek]

Only slaves that are up should transmit netpoll frames, so there is no
need to check to see if a slave is up before enabling netpoll on it.
This resolves a reported failure on active-backup bonds where a slave
interface is down when netpoll was enabled.
