Set WHDR_DONE right before DriverCallback

This patch separates the to_play queue from the done queue.

Note that threading might allow thread #2 to issue DriverCallback before thread
#1...  The notification order would be messed up!  There's no solution to this
short of having a unique thread send out all asynchronous notifications (cf.
bug #3930, it looks like native actually does that).
