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

Log Message:
several small tweaks:
- use MSIX if available
- fix off-by-one for nluns/ntargets (code inspection, not actual effect)
- when virtio_enqueue_reserve() fails, do not execute vioscsi_req_put()
  and hence virtio_dequeue_commit() as there is nothing to commit, just
  unload the xs and return; also report XS_RESOURCE_SHORTAGE, it's
  semi-normal situation
- set status/resid in vioscsi_req_done() before the switch, so that
  the override for VIRTIO_SCSI_S_BAD_TARGET actually has effect
- g/c vioscsi_req_put(), call the appropriate cleanup routines directly
- stop initializing id/task_attr in vioscsi_req_get(), it's overwritten
  in vioscsi_scsipi_request() anyway
