[NET_SCHED]: sch_ingress: remove useless printk

The printk about ingress qdisc registration error can't be triggered
under normal circumstances. Since register_qdisc only fails for two
identical registrations, the only way to trigger it is by loading the
sch_ingress modules multiple times under different names, in which
case we already return -EEXIST to userspace.
