    kernel - Fix vn_syncer_add panic with UFS
    
    * The new VONWORKLST requirements were expanded to include VOBJDIRTY
      for both the standard syncer and the new syncer.  There was a path
      in the VM system which could clear VOBJDIRTY but failed to resynchronize
      VONWORKLST which could cause UFS to accidently leave a vnode on the
      syncer list after reclamation, causing a crash.
    
    * Fix the VM path.
