[PATCH][next] apparmor: Fix incorrect profile->signal range check

[Colin Ian King]

The check on profile->signal is always false, the value can never be
less than 1 *and* greater than MAXMAPPED_SIG. Fix this by replacing
the logical operator && with ||.

Fixes: 84c455decf27 ("apparmor: add support for profiles to define the kill signal")
