strmbase: Swap the lock order in IPin::EndFlush(). 

This more closely resembles the threading model prescribed by the DirectX SDK
documentation. In particular, the page "Flushing Data" recommends that
IPin::BeginFlush() do the following steps in order:

1. take the filter lock
2. signal the streaming thread to complete
3. take the streaming lock, if necessary
