There are a few problems with the error handling in this function. They
mostly center around the alloc_ordered_workqueue() allocation.
1) If that allocation fails or if the kcalloc() prior to it fails then
it leads to a NULL dereference when we call
destroy_workqueue(mhi_cntrl->hiprio_wq).
2) The error code is not set.
3) The "mhi_cntrl->mhi_cmd" allocation is not freed.
The error handling was slightly confusing and I re-ordered it to be in
the exact mirror/reverse order of how things were allocated. I changed
the label names to say what the goto does instead of describing where
the goto comes from.

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.
