Allow the flexfiles error handling to recognise NFS level errors (as
opposed to RPC level errors) and handle them separately. The main
motivator is the NFSERR_PERM errors that get returned if the NFS client
connects to the data server through a port number that is lower than
1024. In that case, the client should disconnect and retry a READ on a
different data server, or it should retry a WRITE after reconnecting.
