dev2udev() returns a CDEV udev_t, but we use block io in savecore. Savecore
also gets the device by st_rdev, which is alright except for the fact that
the sysctl kern.dumpdev passed out a char device. This is a workaround.
Sorry for not committing the fix earlier, before people started having
problems.
