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.
