usb-serial: Remove double call to qemu_chr_add_handlers( NULL )

usb-serial has a qdev chardev property, and hw/qdev-properties-system.c
already contains:

static void release_chr(Object *obj, const char *name, void *opaque)
{
    DeviceState *dev = DEVICE(obj);
    Property *prop = opaque;
    CharDriverState **ptr = qdev_get_prop_ptr(dev, prop);
    CharDriverState *chr = *ptr;

    if (chr) {
        qemu_chr_add_handlers(chr, NULL, NULL, NULL, NULL);
        qemu_chr_fe_release(chr);
    }
}

So doing the qemu_chr_add_handlers(s->cs, NULL, NULL, NULL, NULL); from
the usb handle_destroy function too will lead to it being done twice.
