This patch does the following changes
1. convert printk(KERN_DEBUG.. to netdev_dbg() if we have net_device object
   or convert to dev_dbg() if we have device object.
2. convert printk(KERN_WARNING.. to netdev_warn() if we have net_device object
   or convert to dev_warn() if we have device object
3. convert printk() to pr_*
