[PATCH 2.6] vlan - device refcount bug.

[Stephen Hemminger <shemminger@xxxxxxxx>]

If you rmmod a network device that is in a vlan, the system hangs waiting
for the refcount to go to zero, because it is -1.  The problem is that the
vlan notifier does an extra dev_put in NETDEV_UNREGISTER case of notifier.
