net/ice: fix reading of RSS hash key

The ICE driver returns only the first 40 bytes of its 52-byte RSS
hash key. This patch corrects this behavior.

Yuying Zhang <yuying.zhang@intel.com> wrote the original patch, and
Michel Machado <michel@digirati.com.br> back ported it to
Gatekeeper's custom DPDK.

This patch addresses one of the problems found with
the Intel 810 NIC. The following issue centralizes all the problems
related with this NIC:
