[igt-dev] [PATCH i-g-t v25 34/35] tests/perf.c: Remove buffer from batch

Currently we need to ensure intel_buf is a part of single ibb due
to fact it is acquiring address from allocator so we cannot keep
it in two separate ibbs (theoretically it is possible when different
ibbs would be in same context but it is not currently implemented).
