The way how iomap_dio_can_use_fua and the caller is structured is a bit confusing, as the main guarding condition is hidden in the helper, and the secondary conditions are split between caller and callee. Refactor the code, so that iomap_dio_bio_iter itself tracks if a write might need metadata updates based on the iomap type and flags, and then have a condition based on that to use the FUA flag. Note that this also moves the REQ_OP_WRITE assignment to the end of the branch to improve readability a bit.

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.
