commit fd9edbdbdcde6b489ce59f326755ef16a2ffadd7 upstream. During the maple tree conversion of nommu, an error in counting the VMAs was introduced by counting the existing VMA again. The counting used to be decremented by one and incremented by two, but now it only increments by two. Fix the counting error by moving the increment outside the setup_vma_to_mm() function to the callers.

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.
