eventdev: reserve space in main structs for extension
The struct rte_eventdev and rte_eventdev_data are supposed
to be used internally only, but there is a chance that
increasing their size would break ABI for some applications.
In order to allow smooth addition of features without breaking
ABI compatibility, some space is reserved.
