firewire: cdev: fix fw_cdev_event_bus_reset emission after local config ROM changes
When a descriptor was added or removed to the local node's config ROM, userspace clients which had a local node's /dev/fw* open did not receive any fw_cdev_event_bus_reset for poll()/read() consumption. The cause was that the core-device.c facility which re-reads the config ROM of the bus reset initiator node missed to call the fw_device update function. The fw_units are destroyed and newly added, but their parent stays and needs to be updated. Reported-by: Jay Fenlason <fenlason@redhat.com> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
