description:
Some NFS servers return RPC_PROGNOTREGISTERED instead of RPC_PROGVERSMISMATCH
when they don't support EXT_RQUOTAVERS but support RQUOTAVERS, so
retry with RQUOTAVERS for both RPC_PROGNOTREGISTERED and RPC_PROGVERSMISMATCH
return code.
Fix issue against a NetApp server reported by 6bone on current-users
