VMA binding to GGTT is now asynchronous in CHV / BXT+VDT enviroments, then vma->resource->page_sizes_gtt the test uses as shift count may still be not populated (equal 0) after i915_vma_pin() returns. Wait for VMA bind completion in those cases to avoid shift-out-of-bounds kernel warnings and the test case failing with -EBADSLT.
