The core code needs to compute the udata so we may as well pass it in the uverbs_attr_bundle instead of on the stack. This converts the simple case of write_ex() which already has a core calculation. Also change the write() path to use the attrs for ib_uverbs_init_udata() instead of on the stack. This lets the write to write_ex compatibility path continue to follow the lead of the _ex path.

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.
