vdpa/mlx5: Delete control vq iotlb in destroy_mr only when necessary

Browse source

[ Upstream commit ad03a0f44c ]

mlx5_vdpa_destroy_mr can be called from .set_map with data ASID after
the control virtqueue ASID iotlb has been populated. The control vq
iotlb must not be cleared, since it will not be populated again.

So call the ASID aware destroy function which makes sure that the
right vq resource is destroyed.
