printk: git rid of [sched_delayed] message for printk_deferred
Commit 458df9fd4815 ("printk: remove separate printk_sched buffers and use printk buf instead") 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(). The prefix is useless since 458df9fd4815 anyway since from that moment printk_deferred() inserts the message into the kernel printk buffer immediately. So if the message eventually gets printed to console, it is printed in the correct order with other messages and there's no need for any special prefix. And if the kernel crashes before the message makes it to console, then prefix in the printk buffer doesn't make the situation any better.
