Correctly handle reusing reset picture buffers.

Pending output samples are marked as ready for reuse in
DXVAVideoDecodeAccelerator::Reset. CopySurfaceComplete hasn't executed
to acquire the keyed mutex, so it shouldn't be released. The
incrementing of keyed_mutex_value_ also needs to be moved to someplace
where it's certain that it will be executed even if CopySurfaceComplete
is skipped.
