Read statistics of a vdpa device. The specific data is a received as a
pair of attribute name and attribute value.
Examples:
1. Read statistics for the virtqueue at index 1
$ vdpa dev vstats show vdpa-a qidx 1
vdpa-a:
vdpa-a: queue_type tx received_desc 321812 completed_desc 321812
2. Read statistics for the virtqueue at index 16
$ vdpa dev vstats show vdpa-a qidx 16
vdpa-a: queue_type control_vq received_desc 17 completed_desc 17
3. Read statisitics for the virtqueue at index 0 with json output
$ vdpa -j dev vstats show vdpa-a qidx 0
{"vstats":{"vdpa-a":{"queue_type":"rx","received_desc":114855,"completed_desc":114617}}}
4. Read statistics for the virtqueue at index 0 with preety json
output
$ vdpa -jp dev vstats show vdpa-a qidx 0
vdpa -jp dev vstats show vdpa-a qidx 0

"vstats": {
"vdpa-a": {
