Failure handling in iova_cache_get() is a little messy, and we'd like to add some more to it, so let's tidy up a bit first. By leaving the hotplug handler until last we can take advantage of kmem_cache_destroy() being NULL-safe to have a single cleanup label. We can also improve the error reporting, noting that kmem_cache_create() already screams if it fails, so that one is redundant.

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.
