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.
