It'd be nice to hide details of how rsrc nodes are used by a request from rsrc.c, specifically which request fields store them, and what bits are signifying if there is a node in a request. It rather belong to generic request handling, so move the helper to io_uring.c. While doing so remove clearing of ->buf_node as it's controlled by REQ_F_BUF_NODE and doesn't require zeroing.

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.
