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

Browse source 
[ 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 fbe313884d (tools/power/x86/intel_pstate_tracer: Free the
trace buffer memory) introduced a bug that breaks that option.

Commit 35459105de (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.

Fixes: 35459105de (tools/power/x86/intel_pstate_tracer: Add optional ...)
