net/mlx5: increase number of supported DV sub-flows

Testpmd example that could not work with existing number of DV sub-flows:

dpdk-testpmd  -a PCI,dv_xmeta_en=1,l3_vxlan_en=1,dv_flow_en=1 -- \
              -i  --nb-cores=4  --rxq=5 --txq=5

set sample_actions 1 mark id 43704 / \
rss queues 3 0 1 1 end types ipv4 ipv4-other udp tcp ipv4-udp end / \
end

flow create 0 priority 15 group 271 ingress \
pattern mark id spec 16777184 id mask 0xffffff / end \
actions sample ratio 1 index 1 / queue index 0 / end

Increase number of supported DV sub-flows to 64
