[PATCH 07/14] spapr/xive: Rework error handling in kvmppc_xive_get_queues()

[Greg Kurz]

Since kvmppc_xive_get_queue_config() has a return value, convert
kvmppc_xive_get_queues() 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.
