comedi vmk80xx: Style improvements
Style improvements to comedi driver vmk80xx:
* One variable definition per line
* Block quotes start and end with near-empty lines
* If..else statements use braces for both branches
* Egregious blank lines removed
* Use if..else rather than goto where trivial
* Don't put function return type on a separate line
