bonding: toggle bond admin state may cause hw link state to down

For bond interface, we set hardware link state to up initially when
admin state is set to up. Thereafter, if we toggle the admin state to
down and up, we require at least one active member in the bond prior
to bringing up the hardware state which is inconsistent. The fix is to
remove the unnecessary condition.

This is a rework of the original proposed patch which is more complex
and could be tricky to get it right
