9p: Add datasync to client side TFSYNC/RFSYNC for dotl
SYNOPSIS size[4] Tfsync tag[2] fid[4] datasync[4] size[4] Rfsync tag[2] DESCRIPTION The Tfsync transaction transfers ("flushes") all modified in-core data of file identified by fid to the disk device (or other permanent storage device) where that file resides. If datasync flag is specified data will be fleshed but does not flush modified metadata unless that metadata is needed in order to allow a subsequent data retrieval to be correctly handled.
