You need to add a method to detach the device:
        /* Device interface */
        DEVMETHOD(device_probe,         flaprobe),
        DEVMETHOD(device_attach,        flaattach),

there needs to be a device_detach line here.  Look at other drivers
on how to add this.  One the detach can be successfully called, kldunload
should then start working.
