[PATCH] bonding: incorrect bonding state reported via ioctl

This is a small fix-up to finish out the work done by Jay Vosburgh to add
carrier-state support for bonding devices.  The output in
/proc/net/bonding/bondX was correct, but when collecting the same info via
an iotcl it could still be incorrect.
