Zhang Xiaoxu ca08d0eac0 cifs: Fix memory leak on the deferred close 
xfstests on smb21 report kmemleak as below:

  unreferenced object 0xffff8881767d6200 (size 64):
    comm "xfs_io", pid 1284, jiffies 4294777434 (age 20.789s)

When cancel the deferred close work, we should also cleanup the struct
cifs_deferred_close.

Fixes: 9e992755be ("cifs: Call close synchronously during unlink/rename/lease break.")
Fixes: e3fc065682 ("cifs: Deferred close performance improvements")

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.
