Mathieu Duponchelle 07fcd4d1b5 queue2: don't post unnecessary buffering message, refine locking
This is a follow up to review comments in !297

+ The posting of the buffering message in READY_TO_PAUSED isn't
  needed, removing it made the test fail, but the correct fix
  was simply to link elements together

+ Move code to relock the queue and set last_posted_buffering_percent
  and percent_changed inside the buffering_post_lock in create_write().
  This makes locking consistent with post_buffering()
