[PATCH] tools/power/x86/intel_pstate_tracer: Fix non root execution for post processing a trace file.

From: Doug Smythies
Date: Tue Dec 18 2018 - 02:34:25 EST

This script is supposed to be allowed to run with regular user privileges
if a previously captured trace is being post processed.

Commit fbe313884d7ddd73ce457473cbdf3763f5b1d3da
tools/power/x86/intel_pstate_tracer: Free the trace buffer memory
introduced a bug that breaks that option.

Commit 35459105deb26430653a7299a86bc66fb4dd5773
tools/power/x86/intel_pstate_tracer: Add optional setting of trace buffer memory allocation
moved the code but kept the bug.

This patch fixes the issue.
