4.19-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 663546903c835fe46308b1b1e53d32d1f2b33da9 ]
This script is supposed to be allowed to run with regular user privileges if a previously captured trace is being post processed.
Commit fbe313884d7d (tools/power/x86/intel_pstate_tracer: Free the trace buffer memory) introduced a bug that breaks that option.
Commit 35459105deb2 (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.
