[PATCH] printk: git rid of [sched_delayed] message for printk_deferred

[Markus Trippelsdorf]

commit 458df9fd hardcodes printk_deferred() to KERN_WARNING and inserts
the string "[sched_delayed] " before the actual message.
However it doesn't take into account the KERN_* prefix of the message,
that now ends up in the middle of the output:

 [sched_delayed] ^a4CE: hpet increased min_delta_ns to 20115 nsec

Fix this by just getting rid of the "[sched_delayed] " scnprintf().
