Of the 22 (!!!) local variables declared in this function only 9 have function-wide context. Of the remaining 13, 12 are needed in the main while loop of the function and 1 is needed in a tiny if branch, only in case we have prealloc extent. This commit reduces the lifespan of every variable to its bare minimum. It also renames the 'nolock' boolean to freespace_inode to clearly indicate its purpose.

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.
