 Module Name:	src
 Committed By:	uwe

 Modified Files:
 	src/sys/dev/pci: if_vioif.c
 
 Log Message:
 vioif_start() - do not call virtio_enqueue_abort() after error from
 virtio_enqueue_reserve(), as it's already done by the latter, so we
 ended up with a kind of "double free" that messed up out free list of
 vq_entry's.
 
 This is even documented in a "typical usage" comment in virtio.c (and
 those quotes are not intended to be sarcastic).
