bridge: master device stuck in no-carrier state forever when in user-stp mode
When in user-stp mode, bridge master do not follow state of its slaves, so after the following sequence of events it can stuck forever in no-carrier state: 1) turn stp off 2) put all slaves down - master device will follow their state and also go in no-carrier state 3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode) Now bridge master won't follow slaves' state and will never reach running state. This patch solves the problem by making user-stp and kernel-stp behavior similar regarding master following slaves' states.
