[dpdk-dev] [PATCH] hash: fix compilation for gcc 4.4/4.5

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

gcc 4.4 and 4.5 throws following error:
rte_cuckoo_hash.c:145: error: flexible array member in otherwise empty struct.

This is due to empty length in flexible array, which has been changed to use
size 0 in the declaration of the array.

Fixes: 48a399119619 ("hash: replace with cuckoo hash implementation")
