Yicong Yang b277e14253 perf hisi-ptt: Fix one memory leakage in hisi_ptt_process_auxtrace_event() 
[ Upstream commit 1bc479d665 ]

ASan complains a memory leakage in hisi_ptt_process_auxtrace_event()
that the data buffer is not freed. Since currently we only support the
raw dump trace mode, the data buffer is used only within this function.
So fix this by freeing the data buffer before going out.

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.
