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.
