pcm: direct: Check xrun/suspend before the slave hwptr update

The xrun/suspend may happen at any time and we should check it right
after the slave hwptr update (but before the actual sync_ptr update in
direct pcm side).  Otherwise the hwptr value may be screwed and get
unexpected large read/write.
