gianfar: ethernet vanishes after restoring from hibernation
If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.
For example:
~# ifconfig eth0 down
~# echo disk > /sys/power/state
<trigger a restore from hibernation>
~# ifconfig eth0 up
SIOCSIFFLAGS: No such device
This happens because the restore function bails out early upon
finding devices that were not up at hibernation. In doing so,
it never gets to the netif_device_attach call at the end of
the restore function. Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.
