[PATCH net 3/3] bonding:force to use primary slave

When we set primary slave with module parameters, bond will always use this
primary slave as active slave.

But when we modify primary slave via sysfs, it will call
bond_should_change_active() and take into account primary_reselect.

And I think we should use the new primary slave as the new active slave
regardless of the value of primary_reselect.
Thus the behavior is the same with module parameters and meets the
administrator's expectation.
