> Fix the return values of these hypercall helpers so they return
> a negated errno either directly or via hv_result_to_errno().
> 
> Update the callers to check for errno instead of using
> hv_status_success(), and remove redundant error printing.
> 
> While at it, rearrange some variable declarations to adhere to style
> guidelines i.e. "reverse fir tree order".
