NFS: Clean up NFS writeback flush code
The only user of nfs_sync_mapping_range() is nfs_getattr(), which uses it to flush out the entire inode without sending a commit. We therefore replace nfs_sync_mapping_range with a more appropriate helper. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
