Ideally its impossible because both aren't related. But
the common idiom is to search for the device with the
same name.

Something like:

bool is_the_dump_device(device_t dev)
{
	const char *driver;
	device_t d;

	if (bdev_type(dumpdev) != D_DISK)
		return false;

	driver = devswblk2name(major(dumpdev));
	d = device_find_by_driver_unit(driver, DISKUNIT(dumpdev));

	return d == dev;
}
