[PATCH 5/8] apparmor, virt-aa-helper: Explicit denies for host devices

[Stefan Bader <stefan.bader@xxxxxxxxxxxxx>]

From: Felix Geyer <fgeyer@xxxxxxxxxx>

Add explicit denies for disk devices to avoid cluttering dmesg with
(acceptable) denials (merged with a second patch which added more
disk device names).
