title: Detach ItemTouchHelper from RecyclerView
body: <p>I have a <code>RecyclerView</code> with a working <code>ItemTouchHelper</code>. Everything works great, but I am wondering if there is a way I can detach the <code>ItemTouchHelper</code> from the <code>RecyclerView</code> without re-creating the list?  For fun, this is the code I'm using to attach:</p>
  <pre><code>ItemTouchHelper.Callback callback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT)
  {
      ...
  };
  mItemTouchHelper = new ItemTouchHelper(callback);
  mItemTouchHelper.attachToRecyclerView(mPasswordList);
  </code></pre>
  <p>Ideally, I'd like to check a preference in say <code>onResume()</code> of the Activity this <code>RecyclerView</code> lives in and detach the <code>ItemTouchHelper</code> based on that.</p>
