Now that SRCU is gone from IPMI, it can no longer be sloppy about locking. Use the users mutex now when sending a message, not the big ipmi_interfaces mutex, because it can result in a recursive lock. The users mutex will work because the interface destroy code claims it after setting the interface in shutdown mode. Also, due to the same changes, rework the refcounting on users and interfaces. Remove the refcount to an interface when the user is freed, not when it is destroyed. If the interface is destroyed while the user still exists, the user will still point to the interface to test that it is valid if the user tries to do anything but delete the user.

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 reStructuredText 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.
