spapr/xive: Rework error handling of kvmppc_xive_source_reset()

Since kvmppc_xive_source_reset_one() has a return value, convert
kvmppc_xive_source_reset() to use it for error checking. This
allows to get rid of the local_err boiler plate.

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