Subject: [PATCH linux-next] ia64/kernel/iosapic: replace a printk + WARN_ON() to a WARN()

From: jing yangyang <jing.yangyang@....com.cn>

Replace a printk+WARN_ON() by a WARN(); this increases the chance of 
the string making it into the bugreport

This issue was detected with the help of Coccinelle.
