[dpdk-dev] hash: fix incorrect bucket size usage
Commit Message
Multiwriter insert function was using a fixed value for
the bucket size, instead of using the
RTE_HASH_BUCKET_ENTRIES macro, which value was changed
recently (making it inconsistent in this case).
Fixes: be856325cba3 ("hash: add scalable multi-writer insertion with Intel TSX")
