tick/sched: Combine WARN_ON_ONCE and print_once

Browse Source 
When the WARN_ON_ONCE() triggers, the printk() of the additional
information related to the warning will not happen in print level
"warn". When reading dmesg with a restriction to level "warn", the
information published by the printk_once() will not show up there.

Transform WARN_ON_ONCE() and printk_once() into a WARN_ONCE().
