After a change to the put_user() macro on x86, kernel test robot has started sending me complaints (from sparse) about passing kernel pointers to put_user(). So add the __user annotations to the various casts in fitpc2_wdt_ioctl(), and while in here, also make the write method actually match the prototype of file_operations::write.

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.
