Liu Shixin 203a55f04f ubifs: Fix memory leak in ubifs_sysfs_init()
When insmod ubifs.ko, a kmemleak reported as below:

 unreferenced object 0xffff88817fb1a780 (size 8):
   comm "insmod", pid 25265, jiffies 4295239702 (age 100.130s)
   hex dump (first 8 bytes):

     [<ffffffff88e00087>] entry_SYSCALL_64_after_hwframe+0x63/0xcd

When kset_register() failed, we should call kset_put to cleanup it.

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.
