Avoid batch mode warnings in case of non-packet procesing elements

[piotrjurkiewicz]

Is there any point in printing batch mode warnings for elements which do not process packets?

click_driver@@ControlSocket won't be in batch mode because no element produces or sends batches to it.
click_driver@@ControlSocket@1 won't be in batch mode because no element produces or sends batches to it.

Can FastClick automatically detect such elements and do not print warnings for them?

No...

I meant it's not currently done but I'll do it.
