tools/power turbostat: Fix file pointer leak
Currently if a fscanf fails then an early return leaks an open
file pointer. Fix this by fclosing the file before the return.
Detected using static analysis with cppcheck:
tools/power/x86/turbostat/turbostat.c:2039:3: error: Resource leak: fp [resourceLeak]
Fixes: eae97e053fe3 ("tools/power turbostat: Support thermal throttle count print")
