vdpa/mlx5: Don't reset VQs more than necessary
The vdpa device can be reset many times in sequence without any
significant state changes in between. Previously this was not a problem:
VQs were torn down only on first reset. But after VQ pre-creation was
introduced, each reset will delete and re-create the hardware VQs and
their associated resources.
To solve this problem, avoid resetting hardware VQs if the VQs are still
in a blank state.
