powerpc/xive: add error return value to xive_smp_probe()

Browse source

xive_smp_probe() calls xive_init_ipis() which can fail, but its
return value is currently ignored.  Change xive_smp_probe() to
return int so that errors can be propagated to callers.

This is a preparatory patch for the next one.

No functional change yet; the return value is always 0 at this point.
