vdpa/mlx5: Use async API for vq query command
Switch firmware vq query command to be issued via the async API to
allow future parallelization.
For now the command is still serial but the infrastructure is there
to issue commands in parallel, including ratelimiting the number
of issued async commands to firmware.
A later patch will switch to issuing more commands at a time.
