Anders Roxell 0761b1f5bf powerpc/mm: Rearrange if-else block to avoid clang warning 
commit d78c8e3289 upstream.

Clang warns:

  arch/powerpc/mm/book3s64/radix_tlb.c:1191:23: error: variable 'hstart' is uninitialized when used here
    __tlbiel_va_range(hstart, hend, pid,
                      ^~~~~~
  arch/powerpc/mm/book3s64/radix_tlb.c:1191:31: error: variable 'hend' is uninitialized when used here
    __tlbiel_va_range(hstart, hend, pid,
                              ^~~~

Rework the 'if (IS_ENABLE(CONFIG_TRANSPARENT_HUGEPAGE))' so hstart/hend
is always initialized to silence the warnings. That will also simplify
the 'else' path. Clang is getting confused with these warnings, but the
warnings is a false-positive.

README 

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.

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.
