[PATCH] tools/power turbostat: fix leak of file descriptor on error return path

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

Currently the error return path does not close the file fp and leaks
a file descriptor. Fix this by closing the file.

Fixes: 5ea7647b333f ("tools/power turbostat: Warn on bad ACPI LPIT data")
