qeth: initialize net_device with carrier off 

/sys/class/net/<interface>/operstate for an active qeth network
interface offen shows "unknown", which translates to "state UNKNOWN
in output of "ip link show". It is caused by a missing initialization
of the __LINK_STATE_NOCARRIER bit in the net_device state field.
This patch adds a netif_carrier_off() invocation when creating the
net_device for a qeth device.
