V4L/DVB (6594): Add tuner_err macro

Some tuners, like xc3028, need to print error messages. Instead of declaring
local macros, create a tuner global macro for printing tuner errors.

To preserve CodingStyle on all tuner_macros, a few CodingStyle violations were
fixed at the other macros:
	- lines with more than 80 columns
	- two statements at the same line

The patch also removes the CodingStyle violation of having emacs declarations
inside de source code (CodingStyle chapter 18).
