Tong Tiangen 313b18c774 memory tier: release the new_memtier in find_create_memory_tier()
commit 93419139fa14124c1c507d804f2b28866ebee28d upstream.

In find_create_memory_tier(), if failed to register device, then we should
release new_memtier from the tier list and put device instead of memtier.

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.
