[PATCH v2] ethdev: remove header split Rx offload

[xuan.ding@intel.com]

From: Xuan Ding <xuan.ding@intel.com>

As announced in the deprecation note, this patch removes the Rx offload
flag 'RTE_ETH_RX_OFFLOAD_HEADER_SPLIT' and 'split_hdr_size' field from
the structure 'rte_eth_rxmode'. Meanwhile, the place where the examples
and apps initialize the 'split_hdr_size' field, and where the drivers
check if the 'split_hdr_size' value is 0 are also removed.

User can still use `RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT` for per-queue packet
split offload, which is configured by 'rte_eth_rxseg_split'.
