  Log:
  Fix if_vr's handling of vr_encap failures.  3 parts:
  
  - Don't bother setting OACTIVE when the descriptors are all full
    or there's a vr_encap failure, it doesn't help anything.
  - Correctly roll back on the descriptor list after a failure
    so as not to corrupt the list.
  - Add a missing VR_UNLOCK().
  
  Without these changes, vr_encap failure (which is assured during
  a low mbuf situation) would result in the card locking until
  the watchdog could fire.
