[igt-dev] [PATCH i-g-t v2 21/23] tests/gem_render_copy_redux: Adopt to use with intel_bb and allocator

[Zbigniew Kempczyński]

As intel_bb has some strong requirements when allocator is in use
(addresses cannot move when simple allocator is used) ensure gem
buffer which is created from flink will reacquire new address.
