media: cxusb: fix several coding style issues
As this driver had a major change, let's take the opportunity and do some coding style cleanup, in order to make it compliant with Kernel's style. This patch was partially done with the help of two tools: ./scripts/checkpatch.pl --fix-inplace --strict astyle --indent=tab=8 --style=linux But manually adjusted in order to fit our style.
