Burn the old opcode to avoid any potential old userspace running the old
API to get weird errors. Changing the opcodes will make them fail right
away.

This is just a precaution, there no upstream users of these interfaces
yet and the only user is Android, but we don't expect anyone trying to
run android userspace and all it dependencies on top of upstream kernels.

Moreover Android should be converted to use upstream sync_files.
