ibm_newemac: emac_close() needs to call netif_carrier_off()
When ibm_newemac netdev instance is shutdown with "ifconfig down", the netdev interface does not go properly down. netif_carrier_ok() keeps returning TRUE even after "ifconfig down". The problem can be seen when ibm_newemac instances are slaves of a bonding interface. The bonding interface code uses netif_carrier_ok() to determine the link status of its slaves. When ibm_newemac slave is shutdown with "ifconfig down", the bonding interface won't detect any link status change because netif_carrier_ok() keeps returning TRUE.
