[ovs-dev] [PATCH] rstp/stp: Unref the rstp/stp when bridges destroyed.

[nickcooper-zhangtonghao]

When bridges destroyed, which stp enabled, you can
still get stp info via the command 'ovs-appctl stp/show'.
And the rstp is also in the same case. We should unref
them. The rstp/stp ports have been unregistered via
'ofproto_port_unregister' function when ports destroyed.
We will unref rstp/stp struct in the 'destruct' of
ofproto-dpif provider.
