    firewire: Initialize firewire_devclass in fw_modevent.
    
    The use of devclass_get_softc() combined with cdev unit numbers is
    probably not ideal (probably should be initializing si_drv1 when each
    cdev is created instead), but it looks like a bit of a PITA to do, so
    just initialize the devclass explicitly instead.
