drm/i915/gvt: Refine error handling for intel_vgpu_pin_mm

Browse source

When it is failed in shadow_mm, the pin_count should rollback
to the original states before return.

v2:
- split the mixed several error paths for better review. (Zhenyu)

v3:
  increase the pincount after shadow success. (Zhenyu)
