[igt-dev] [PATCH i-g-t 33/35] tests/gem_render_copy_redux: Adopt to use with intel_bb and allocator

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

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.
