> gvt_err should be used only for the very few critical error message
> during host i915 drvier initialization. This patch
> 1. removes the redundant gvt_err;
> 2. creates a new gvt_vm_err to show errors caused by vgpu;
> 3. replaces the most gvt_err with gvt_vm_err;
> 4. leaves very few gvt_err for dumping gvt error during host gvt
> initialization.
gvt_vm_err -> gvt_vgpu_err
