hw/qdev: Abort rather than ignoring errors adding device properties 

Instead of ignoring any errors that occur when adding properties
to a new device in device_initfn(), check for them and abort if any
occur. The most likely cause is accidentally adding a duplicate
property, which is a programming error by the device author.
