[PATCH] net/mlx5: fix connection tracking state item validation

[Khadem Ullah]

Hi Ivan, 

The multi-line block was not closed in brackets due to coding style.

Spec provides values to match (e.g. a given IPv4 address) in rte_flow rules. 
Incase of the flowing rte_flow rule, spec provides in 
mlx5_flow_dv_validate_item_aso_ct the conntrack state to be validated. 

The following is a valid rule and it should be offloaded. 

flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 1 / end actions queue index 5 / end

and the following is an invalid rule which should be rejected, as there is no conntract state corresponds to 10.
flow create 0 group 5 ingress pattern eth / ipv4 / tcp / conntrack is 10 / end actions queue index 5 / end
