The stlink commands for buffer read/write carry the associated CSW value that has to be used. We can dequeue any CSW write request and add the CSW in the following buffer read/write. In preparation to next patch that uses stlink commands misc-rw (commands that don't handle CSW value), let's dequeue only those CSW write that don't change csw_default. Keep a local cache of last csw_default. Tag the queued CSW writes that change csw_default. Dequeue only the un-tagged CSW writes. On buffer read/write commands, limiting the dequeued CSW write surely adds a performance penalty. But csw_default is not changed often so the penalty is not significant.
