[PATCH 5.2 096/124] tools/power turbostat: fix leak of file descriptor on error return path

[Greg Kroah-Hartman]

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

[ Upstream commit 15423b958f33132152e209e98df0dedc7a78f22c ]

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")
