net/mlx5: Simplify matching group searches

Browse source

Instead of using two different structs for searching groups with the
same match, use a single struct and thus simplify the code, make it more
readable and smaller size which means less code cache misses.

         text    data     bss     dec     hex
before: 35524    2744       0   38268    957c
after:  35038    2744       0   37782    9396

When testing add 70000 rules, delete all the rules, and repeat three
times taking the average, we get (time in seconds):

Before the change: insert 16.80, delete 11.02
After the change:  insert 16.55, delete 10.95
