Staging: xgifb: Fixed coding style issues.
Not all warnings were silenced. One of them is a typedef in vb_ext.h which I think seems alright. The other warnings in vb_ext.c I left there because that would involve changing a bit of the logic in the code. IMHO though I think the functions are too complicated (i.e. the if/else are too deep within a big function.) and can probably be split.
