[PATCH] tools/power turbostat: close file after use

[Tom Rix]

The cppcheck reports this issue
turbostat.c:2039]: (error) Resource leak: fp

When the fscanf fails an error is returned without closing fp.
Move the fclose so even if the fscanf fails, the file will be closed.

Fixes: eae97e053fe3 ("tools/power turbostat: Support thermal throttle count print")
