Colin Ian King 2ebf6f5946 tools/power turbostat: Fix file pointer leak
[ Upstream commit 5e5fd36c58d6c820f7292ee492c3731c9a104a41 ]

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]
