Conghui Chen ca925f0dd4 dm: storage: change DISCARD to synchronous mode ...

For virtio-blk, when the backend is a regular file, the discard
and
is implemented by fallocate(), but this function will not wait for
the discard command handled by disk.
So, add fdatasync to make sure the DISCARD is executed
synchronously.
