NFSv4.1/pnfs: Ensure that writes respect the O_SYNC flag when doing O_DIRECT
If the caller does not specify the O_SYNC flag, then it is legitimate to return from O_DIRECT without doing a pNFS layoutcommit operation. However if the file is opened O_DIRECT|O_SYNC then we'd better get it right. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
