nfsd: make sure data is on disk before calling ->fsync
commit 7211a4e859ad070b28545c06e0a6cb60b3b8aa31 upstream.
nfsd is not using vfs_fsync, so I missed it when changing the calling
convention during the 2.6.32 window. This patch fixes it to not only
start the data writeout, but also wait for it to complete before calling
into ->fsync.
