Use the common kernel coding style, so don't use C99 // comments.
If too long, where reasonable, they are shortened as well.
Some old internal comments about date and author of changes are
removed.
This provides a more consistent view and hopefully encourages to
look at it.

This changes only a part of rtl8192u's comments. When this is desired,
one can go about and change the rest of the driver.
