nfs: commit layouts in fdatasync
"fdatasync() is similar to fsync(), but does not flush modified metadata
unless that metadata is needed in order to allow a subsequent data
retrieval to be correctly handled."
We absolutely need to commit the layouts to be able to retrieve the data
in case either the client, the server or the storage subsystem go down.
