bitmap_zero() is called after bitmap_alloc() in perf code. But bitmap_alloc() internally uses calloc() which guarantees that allocated area is zeroed. So following bitmap_zero is unneeded. Drop it. This happened because of confusing name for bitmap allocator. It should has name bitmap_zalloc instead of bitmap_alloc. This series: https://lkml.org/lkml/2018/6/18/841 introduces a new API for bitmap allocations in kernel, and functions there are named correctly. Following patch propogates the API to tools, and fixes naming issue.
