dm: fix the issue that RTVM cannot bring up with io uring
735c81d 
Device model uses polling mode to fetch the virtio blk request in RTVM.
When RTVM brings up with io uring, the threads handling io uring and vq are
not same, which would cause competition. To fix this issue, device
model should handle vq and io uring in the same thread to avoid conflict.
