The PCIs event with PEC 0x0303 or 0x0304 are a request to deconfigure a PCI function, respectively an indication that it was already deconfigured by the platform. If such an event is queued during boot it may happen that the platform has already adjusted the configuration flag of the relevant function in the CLP List PCI Functions result. In this case we might not have configured the PCI function at all and should thus ignore the event. Note that no locking is necessary as event handling only starts after we have fully initialized the zPCI subsystem and scanned all PCI devices listed in the CLP result.
