We only use cpus_set_cap() in update_cpu_capabilities(), where we open-code an analgous update to boot_cpucaps. Due to the way the cpucap_ptrs[] array is initialized, we know that the capability number cannot be greater than or equal to ARM64_NCAPS, so the warning is superfluous. Fold cpus_set_cap() into update_cpu_capabilities(), matching what we do for the boot_cpucaps, and making the relationship between the two a bit clearer. There should be no functional change as a result of this patch.

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.
