Wang Hai 1aa5743125 device-dax/core: Fix memory leak when rmmod dax.ko 
When I repeatedly modprobe and rmmod dax.ko, kmemleak report a
memory leak as follows:

unreferenced object 0xffff9a5588c05088 (size 8):
  comm "modprobe", pid 261, jiffies 4294693644 (age 42.063s)
...

When rmmod dax is executed, dax_bus_exit() is missing. This patch
can fix this bug.

README 

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.
