mainlining shenanigans

Currently for CONFIG_SLUB, if a memcg kmem cache creation is failed and the corresponding root kmem cache has SLAB_PANIC flag, the kernel will be crashed. This is unnecessary as the kernel can handle the creation failures of memcg kmem caches. Additionally CONFIG_SLAB does not implement this behavior. So, to keep the behavior consistent between SLAB and SLUB, removing the panic for memcg kmem cache creation failures. The root kmem cache creation failure for SLAB_PANIC correctly panics for both SLAB and SLUB.

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.
