Inspired by #25664: let's check explicitly for NULL everywhere we do one of those getXYZcon() calls. We usually turn this into EOPNOTSUPP, as when selinux is off (which is supposed to be the only case this can happen according to selinux docs) we otherwise return EOPNOTSUPP in that case. Note that in most cases we have an explicit mac_selinux_use() call beforehand, hence this should mostly not be triggerable codepaths.
