[PATCH] b44: fix carrier detection on bind

[Paul Fertser]

For carrier detection to work properly when binding the driver with a cable
unplugged, netif_carrier_off() should be called after register_netdev(),
not before.

Without this it's quite annoying to boot a laptop without ethernet

route through a non-functional interface (when it's configured to use
static ip).
