This patch also updates 'buffer_split_supported_hdr_ptypes_get()'
dev_ops, for 'rte_eth_buffer_split_get_supported_hdr_ptypes()' etdev API.
This wasn't initially intendent but since API behaviour is not impacted,
I think there is no problem on extending this improvement to this
dev_ops too.

Only better to mention from it in the commit log, I will update it while
merging.

updating as 'sizeof(ptypes[0])' while merging.
