hammer - Disallow modifying ioctls when filesystem is read-only

* Disallow modifying ioctls if the filesystem has been mounted read-only
  or gone into read-only mode due to an I/O error.

* This is only a partial fix.  There are still error-pathing problems
  in numerous procedures, particularly the node locking code, that might
  result in a token life-lock.
