CVS commit: src/sys/dev/pci

["Valeriy E. Ushakov" <uwe%netbsd.org@localhost>]

Module Name:    src
Committed By:   uwe
Date:           Tue Nov 29 21:54:11 UTC 2016

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).
