ixgb: fix link down initial state
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, since without a netif_carrier_off, the stack
assumes carrier_on, but before register_netdev, netlink messages are not
sent out telling link state.
This apparently confused *some* versions of networkmanager.
in addition this driver appeared to need a netif_start_queue at
the end of open.
