NFS: Ensure the server has an up to date ctime before hardlinking
[ Upstream commit 204975036b34f55237bc44c8a302a88468ef21b5 ]
Creating a hard link is required by POSIX to update the file ctime, so
ensure that the file data is synced to disk so that we don't clobber the
updated ctime by writing back after creating the hard link.
