Subject: [PATCH 4.14 02/44] ima: Remove ima_policy file before directory

From: Stefan Berger <stefanb@...ux.ibm.com>

commit f7333b9572d0559e00352a926c92f29f061b4569 upstream.

The removal of ima_dir currently fails since ima_policy still exists, so
remove the ima_policy file before removing the directory.

Fixes: 4af4662fa4a9 ("integrity: IMA policy")
