NFSv4.1/flexfiles: Don't mark the entire deviceid as bad for file errors
If the file was fenced and/or has been deleted on the DS, then we want to retry pNFS after a layoutreturn with error report. If the server cannot fix the problem, then we rely on it to tell us so in the response to the LAYOUTGET. Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
