We change size of structures rte_eth_fdir_info and rte_eth_hash_filter_info.
Application can use these structures for DPDK library API call only in
rte_eth_dev_filter_ctrl() function call. In the patch this function is
modified in the way that it will be compatible with user binary applications
compiled with previous versions of DPDK library.

Thanks,
Kirill.
