On an MST unplug, the MST topology manager state needs to be cleared
so it can properly destroy the current topology. But since the mst
active state is cleared prematurely in the driver, this call is
skipped and on a subsequent plug-in, the topology manager ends up
using stale topology from previous configuration. Incorrect RAD
values are used for sideband, causing them to fail.
This change fixes the order of operations, so the topology manager
state is properly updated on unplug. It also removes a duplicate
hpd notification to usermode.
