 - Don't immediately re-run softdepflush if we didn't make any progress
   on the last iteration.  This can lead to a deadlock when we have
   worklist items that cannot be immediately satisfied.

Reported by: uqs, Dimitry Andric <dimitry@andric.com>

 - Remove some unnecessary debugging code and place some other under
   SUJ_DEBUG.
 - Examine the journal state in softdep_slowdown().
 - Re-format some comments so I may more easily add flag descriptions.
