net/ena: remove unused offload variables

[ upstream commit fa11980449c225a217bf6923e79924edf991cb27 ]

Those variables are being set, but never read. As they seem to be
leftover from the old offloads API and don't have any purpose right
now, they are simply being removed.

Fixes: a4996bd ("ethdev: new Rx/Tx offloads API")
