Greg Kurz 3885ca6688 spapr/xive: Rework error handling of kvmppc_xive_cpu_connect()
Use error_setg_errno() instead of error_setg(strerror()). While here,
use -ret instead of errno since kvm_vcpu_enable_cap() returns a negative
errno on failure.

Use ERRP_GUARD() to ensure that errp can be passed to error_append_hint(),
and get rid of the local_err boilerplate.

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