Later version of 'struct xsk_umem_config' contains additional field

umem with unexpected properties.
We need to clear the whole structure explicitly to avoid this kind
of issues.

Thanks for the patch.
I applied to master.
Thanks, William.
As this is a bug fix it needs to be backported to 2.12.
Best regards, Ilya Maximets.
