Move the CPUID 0x7 masking back into __do_cpuid_func() now that the size of the code has been trimmed down significantly. Tweak the WARN case, which is impossible to hit unless the CPU is completely broken, to break the loop before creating the bogus entry. Opportunustically reorder the cpuid_entry_set() calls and shorten the comment about emulation to further reduce the footprint of CPUID 0x7.

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.
