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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
