bonding: Have bond_check_dev_link examine netif_running

	Some network devices do not call netif_carrier_off when they
are set administratively down.  Have the bonding link check function
also inspect the netif_running state.  Ignore netif_running if the
bond_check_dev_link function is called with "reporting" set, as in that
case it's inspecting the capabilities of the non-netif_carrier device
driver.
