android: camera_stream: Protect buffers initialization by mutex_

Browse source 
The initialization on buffers_ in CameraStrean::configure() is not
protected by mutex_. It is no problem because configure() is not
invoked simultaneously while other functions are called. This
protects it to keep the thread safety consistency for buffers access.
