[PATCH 5.10 017/158] apparmor: fix setting unconfined mode on a loaded profile

[Greg Kroah-Hartman]

From: John Johansen <john.johansen@xxxxxxxxxxxxx>

commit 3bbb7b2e9bbcd22e539e23034da753898fe3b4dc upstream.

When loading a profile that is set to unconfined mode, that label
flag is not set when it should be. Ensure it is set so that when
used in a label the unconfined check will be applied correctly.

Fixes: 038165070aa5 ("apparmor: allow setting any profile into the unconfined state")
