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

[Khadem Ullah]

This patch validate a connection tracking state when matching
'conntrack is' in rte_flow rules. The conntract possible CT states
are SYN_RECV, ESTABLISHED, FIN_WAIT, CLOSE_WAIT, LAST_ACK and
TIME_WAIT. Therefore the maximum possible value to match on
in rte_flow is TIME_WAIT but mlx5 allowed matching on any values.

This patch validate the CT state item.
