bonding: make mii_status sysfs node consistent
The spew in /proc/net/bonding/bond0 uses netif_carrier_ok() to determine mii_status, while /sys/class/net/bond0/bonding/mii_status looks at curr_active_slave, which doesn't actually seem to be set sometimes when the bond actually is up. A mode 4 bond configured via ifcfg-foo files on a Red Hat Enterprise Linux system, after boot, comes up clean and functional, but the sysfs node shows mii_status of down, while proc shows up. A simple enough fix here seems to be to use the same method for determining up or down in both places, and I'd opt for the one that seems to match reality.
