SLUB allocator relies on percpu allocator to initialize its ->cpu_slab during early boot. For that, the dynamic chunk of percpu which serves the early allocation need be large enough to satisfy the kmalloc creation. However, the current BUILD_BUG_ON() in alloc_kmem_cache_cpus() doesn't consider the kmalloc array with NR_KMALLOC_TYPES length. Fix that with correct calculation.

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.
