The lock was disabled recently. This commit gets rid of the dummied out calls. The main reason for removing it is that there is no apparent need for it anymore, and the new FFmpeg vaapi code does not use or provide such a lock (there are some places which we cannot control and which do vaapi API calls, like frame destructors).
