dpdk: set ice PMD RSS key length to 52 bytes for all DPDK versions

ICE driver (Intel E810 NIC) requires/supports 52-byte long RSS key.
The 52 byte key length was mandatory from DPDK 23.11 when Suricata
was starting with independently configured ice PMD.

However, Suricata failed to start when ice PMD was part of
net_bonding PMD, requiring 52 byte RSS key even in DPDK versions
lower than 23.11. Since the support for the longer key is present
since DPDK 19.11 the key is set to 52 bytes for all versions.
