Currently, the device-reset flow doesn't notify the decoder for device change immediately. The decoder might use an invalid sync-object for synchronization. Then, we will hit some assertions. This patch try to make the synchronization flow become fallible, then we could pass the error to the media framework for error handling. MozReview-Commit-ID: BFY32MmOdt0
