vdpa/mlx5: fix device unplug

Browse Source 
The vDPA PCI device unplug process should release all the private
device resources and also to unregister the device.

The device unregistration was missed what remained the device data
invalid in the rte_vhost library.

Unregister the device in unplug process via the remove operation.
