apparmor: Fix logical error in verify_header()
verify_header() is currently checking whether interface version is less than 5 *and* greater than 7, which always evaluates to false. Instead it should check whether it is less than 5 *or* greater than 7. Signed-off-by: Christos Gkekas <chris.gekas@gmail.com> Signed-off-by: John Johansen <john.johansen@canonical.com>
