NFS: Revalidate the file size on a fatal write error
If we suffer a fatal error upon writing a file, which causes us to need to revalidate the entire mapping, then we should also revalidate the file size. Fixes: d2ceb7e57086 ("NFS: Don't use page_file_mapping after removing the page") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
