Issue:
Codelet is executed on Worker which has been disabled for the particular 
task by setting the `workerids`.
This seems to be a regression from version 1.3.7.

StarPU version:
1.3.9

How to reproduce (consider this to be pseudocode, my code is a little 
bit more complex):
```
 // assuming 8 workers
auto *mask = reinterpret_cast<uint32_t *>(calloc(1, sizeof(uint32_t)));
// enable worker 0 and 1
*mask = 3;
auto *task = starpu_task_create()
task->workerids = mask;
task->workerids_len = 1;
...
 starpu_task_submit(task)
 ...
 void Codelet(void *buffers[], void *func_arg) {
   assert(starpu_worker_get_id() == 0 || starpu_worker_get_id() == 1); 
// assert fails, workers 2..8 are also executing this codelet
 }
 ```
