Subject: [PATCH] bonding: bond_check_dev_link() needs to check for netif_running()

bond_check_dev_link() needs to check for netif_running() before checking
the link status of a slave. This needs to be done because some interfaces
keep reporting netif_carrier_ok() == TRUE even after "ifconfig down".
