[v3,3/7] media: mediatek: vcodec: flush decoder before remove all source buffer
Commit Message
Flush decoder will reset all driver to init status, lat and core work
queue will stop to work. If lat or core work queue in working when
remove all source buffer, will lead to remove source buffer again
or buff done with one non-existent source buffer.
