Most functions that are related to kvm_arch_vm_ioctl() already use
"int" as return type to pass error values back to the caller. Some
outlier functions use "long" instead for no good reason (they do not
really require long values here). Let's standardize on "int" here to
avoid casting the values back and forth between the two types.
