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.
