drm/i915/gvt: Audit and shadow workload during ELSP writing
Let the workload audit and shadow ahead of vGPU scheduling, that
will eliminate GPU idle time and improve performance for multi-VM.
The performance of Heaven running simultaneously in 3VMs has
improved 20% after this patch.
v2:Remove condition current->vgpu==vgpu when shadow during ELSP
writing.
