Change some debug messages from printk() to dprintk().

Add KERN_WARNING and KERN_ERR level indicators to other printk()s that
lacked them.

Format printk lines with consistent ("%s/dvb: ", dev->name) prefix.

Fixed dprintk macro, which had an if with no else that wasn't protected
with a do {} while(0) block.  That leads to "if(...) dprintk(); else" not
doing what one would expect.
