vdpa/mlx5: Set an initial size on the VQ

Browse Source 
The virtqueue size is a pre-requisite for setting up any virtqueue
resources. For the upcoming optimization of creating virtqueues at
device add, the virtqueue size has to be configured.

The queue size check in setup_vq() will always be false. So remove it.
