[PATCH v2 3/3] drm/i915/gvt: Remove intel_vgpu_reset_gtt() since no one use it.

[Colin Xu]

Previuos patch split ggtt reset and ppgtt invalidate/destroy logic.
intel_vgpu_reset_gtt() is useless now so remove it.

v2:
- Revise commit message to more accurate description. (Kevin)
- Split patch by logic. (Zhenyu)
