[igt-dev] [PATCH i-g-t v19 10/34] lib/intel_bufops: Removes handle from allocator, change size

[Zbigniew Kempczyński]

1. When buffer is destroyed we don't know in how many allocators it
   was registered. Remove it from any allocator.
2  Additionally buffer size from 32 -> 64 bit was changed to be
   consistent with drm code.
3. Remember buffer creation size to avoid recalculation.
