 (In [27292]) Backport r27281 from trunk to release-0-24-fixes

 Don't call QGLContext::doneCurrent() in MythRenderOpenGL.

     * it should be unnecessary given that makeCurrent always checks the
 correct context is current to the current thread and following the
 threading changes, all of our OpenGL usage should be in the same thread.
     * it breaks playback on certain Windows builds.
     * it has a sizeable performance impact on at least one Intel system.

 Closes #9242
