dsched - Add debugging & fix rare problem conditions

 * Add a bunch of debugging to see whether a particular tdio was
   initialized and to which policy it belongs.

 * Reorder some locking to ensure the whole switch of policy is
   protected as expected.

 * Make sure the tdio from the newest policy is used when there
   are tdios for several scheduling policies in the tdctx->tdio_list.
