Refactor the generation of local variables needed when building
requests, by moving the logic from put_req_nested() into a new
helper put_local_vars(), and use the helper before .attr_put() is
called, thus generating the local variables assumed by .attr_put().
Previously only put_req_nested() generated the variables assumed
by .attr_put(), print_req() only generated the count iterator `i`,
and print_dump() neither generated `i` nor `array`.
This patch fixes the build errors below:

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 reStructuredText 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.
