media: ccs: Remove I²C write retry hack

The I²C retry hack has been there in order to address transient I²C
register write access issues on a few very old sensors and possibly it has
addressed also first I²C access problems (device not responding until a
certain amount of time has passed) but that is now separately handled. The
retry hack has a good potential for introducing hard to debug problems in
updating sensor settings while streaming. Remove it and instead pass those
rare errors to the user space -- which is also what virtually all other
drivers do.
