Fix vulkan app can't display on i915 in VM

In VM if run vulkan on i915, i915_dev->has_fence_reg
is 0, so DRM_IOCTL_I915_GEM_SET_TILING and
DRM_IOCTL_I915_GEM_GET_TILING will never be invoked.
Meanwhile if on dg2, i915_dev->has_fence_reg also is 0.
So the flag 'i915_dev->has_fence_reg' can't be using to
check if invoke GET_TILING,SET_TILING.
Consider if run vulkan app not on dg2, should invoke
GET_TILING,SET_TILING.
