If a master scan occurs while the master is being unregistered,
the devicecs may end up with incorrect and possibly duplicate names,
resulting in kernel warnings. Ensure the master index isn't changed
outside of the scan mutex.
In addition, add some trace events to debug any further issues in this
area.
