Modified Files:
        src/sys/dev/pci: vioscsi.c

Log Message:
refactor error handling in vioscsi_scsipi_request() to avoid the goto maze,
and add missing virtio_enqueue_abort() call when bus_dmamap_load() fails;
abort is only done implicitely when virtio_enqueue_reserve() fails,
must do it explicitely if there is other reason

also now always print error when bus_dmamap_load() or virtio_enqueue_reserve()
fail - the former shouldn't fail due to BUS_DMA_ALLOCNOW, and the latter
shouldn't ever fail now after the maxnsegs fix for virtio_alloc_vq(), so
error there means driver bug
