net/mlx5e: Improve IPsec flow steering autogroup

Flow steering API separates newly created rules based on their
match criteria. Right now, all IPsec tables are created with one
group and suffers from not-optimal FS performance.

Count number of different match criteria for relevant tables, and
set proper value at the table creation.
