This originally came from the aio side, and it's laid out rather oddly. The common case here is that we either get -EIOCBQUEUED from submitting an async request, or that we complete the request correctly with the given number of bytes. Handling the odd internal restart error codes is not a common operation. Lay it out a bit more optimally that better explains the normal flow, and switch to avoiding the indirect call completely as this is our kiocb and we know the completion handler can only be one of two possible variants. While at it, move it to where it belongs in the file, with fellow end IO helpers. Outside of being easier to read, this also reduces the text size of the function by 24 bytes for me on arm64.

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.
