[PATCH 5.15 028/244] apparmor: fix quiet_denied for file rules

From: John Johansen <john.johansen@canonical.com>

commit 68ff8540cc9e4ab557065b3f635c1ff4c96e1f1c upstream.

Global quieting of denied AppArmor generated file events is not
handled correctly. Unfortunately the is checking if quieting of all
audit events is set instead of just denied events.

Fixes: 67012e8209df ("AppArmor: basic auditing infrastructure.")
