virtio-blk: trace vdev so devices can be distinguished
It is hard to analyze trace logs with multiple virtio-blk devices
because none of the trace events include the VirtIODevice *vdev.
This patch adds vdev so it's clear which device a request is associated
with.
I considered using VirtIOBlock *s instead but VirtIODevice *vdev is more
general and may be correlated with generic virtio trace events like
virtio_set_status.
