Jinjie Ruan 2a2dffd911 net: microchip: sparx5: Fix possible memory leaks in vcap_api_kunit 
Inject fault while probing kunit-example-test.ko, the duprule which
is allocated by kzalloc in vcap_dup_rule() of
test_vcap_xn_rule_creator() is not freed, and it cause the memory leaks
below. Use vcap_del_rule() to free them as other functions do 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.
