Subject: [PATCH v3] staging: rtl8192u: Replace printk() with more standardize
 output format.

printk() is the raw way to print output and should be avoided.

For drivers with defined "struct device object", dev_*macro() is
prefer and for "struct netdevice object", netdev_*macro() is prefer over
dev_*macro() to standardize the output format within the subsystem.

If no "struct device object" is defined prefer pr_*macro() over printk().

This patch Replace printk having a log level with the appropriate output
format according to the order of preference.

Changes in v3
*In version2 net_*macro_ratelimited was used which is not helping in
standardizing the output format.

Changes in v2
*change the subject line, driver name was wrong.
