[Decode] Complete cur frame in child thread to unlock res (#6509)

Currently, main thread is responsiable to complete finished frames to
unlock resource, but all available surfaces maybe locked by multi-frame
submission that causes main thread/ application unable to find a free
surface to continue even previous frames decoding are done, so
application has no chance to call async decode api to complete them.
