Greg Kurz d55daadcb8 spapr/xive: Rework error handling of kvmppc_xive_set_source_config()
Since kvm_device_access() returns a negative errno on failure, convert
kvmppc_xive_set_source_config() to use it for error checking. This allows
to get rid of the local_err boilerplate.

Propagate the return value so that callers may use it as well to check
failures.
