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

[Weiping Pan <wpan@redhat.com>]

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.
