uml: driver formatting fixes

Browse Source 
Fix a bunch of formatting violations in the drivers:
	return(n) -> return n
	whitespace fixes
	emacs formatting comment removal
	breaking if(foo) return(n) into two lines

There are also a couple of errno use bugs:
	using errno in a printk when the failure put errno into a local variable
	saving errno after a printk, which can change it
