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.
