e1000: init link state correctly

Browse source 
As reported by Andrew Lutomirski <amluto@gmail.com>

All the intel wired ethernet drivers were calling netif_carrier_off
and netif_stop_queue (or variants) before calling register_netdevice

This is incorrect behavior as was pointed out by davem, and causes
ifconfig and friends to report a strange state before first link
after the driver was loaded.

This apparently confused *some* versions of networkmanager.

Andy tested this for e1000e and confirmed it was working for him.
