This module does some printks with the loglevel missing.
pr_err() takes care of adding the KERN_ERR tag and the module name.
So we can simplify the code and add the missing printk loglevel by
using it.
Also add a #define pr_fmt() to make this work, and remove a few
unnecessary periods at the end of messages and bump the loglevel of
"Unknown bttv card type" from KERN_WARNING to KERN_ERR while at it.
