Update type of prof and prof_mask fields in nix_as_enq_req
from u64 to struct nix_bandprof_s, which is 128 bits wide.
This is to address warnings with compiling with gcc-12 W=1
regarding string fortification.
Although the union of which these fields are a member is 128bits
wide, and thus writing a 128bit entity is safe, the compiler flags
a problem as the field being written is only 64 bits wide.

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.
