Rob N 8f1b7a6fa6 vdev_disk: disable flushes if device does not support it ...

If the underlying device doesn't have a write-back cache, the kernel
will just return a successful response. This doesn't hurt anything, but
it's extra work on the IO taskqs that are unnecessary. So, detect this
when we open the device for the first time.
