Fix exports query with failed RPCs

When the RPC to a node has failed (for whatever reason), we currently
return _FS_UNAVAIL, which means "this node doesn't support
exports". However, that is misleading: all nodes support exports, but
we failed to list them at the moment, so _FS_NODATA (temporary
failure) is more appropriate here.
