drm/i915/gvt: remove the vgpu->released and its sanity check
The life cycle of a vGPU, which is represented by a vfio_device, has been
managed by the VFIO core logic. Remove the vgpu->released, which was used
for a sanity check on the removal path of the vGPU instance. The sanity
check has already been covered in the VFIO core logic.
