Fix thinko in expand_builtin_cilk_detach

[Eric Botcazou]

The 'worker' field has pointer type

  tree worker_type = lang_hooks.types.make_type (RECORD_TYPE);
  tree worker_ptr = build_pointer_type (worker_type);
[...]
  tree worker = add_field ("worker", worker_ptr, parent);

so it needs to be dereferenced before being subject to COMPONENT_REF.

Tested on x86_64-suse-linux, applied on the mainline as obvious.
