Subject: spapr: Fix failure path for attempting to hot unplug PCI bridges

Git-commit: 7aab5899764887f6b0512cb2e5c11bdc2a5d3644

For various technical reasons we can't currently allow unplug a PCI to PCI
bridge on the pseries machine.  spapr_pci_unplug_request() correctly
generates an error message if that's attempted.

But.. if the given errp is not error_abort or error_fatal, it doesn't
actually stop trying to unplug the bridge anyway.

Fixes: 14e714900f6b "spapr: Allow hot plug/unplug of PCI bridges and devices under PCI bridges"
