    dsched_fq - Fix some issues, sprinkle some asserts
    
    * Add some strategic KKASSERT to catch negative values where they aren't
      allowed.
    
    * Avoid certain race conditions by using a local variable instead of
      using the generally accessible one (budget vs dpriv->budgetpb). Only
      set the final value once we are ready.
