net/mlx5e: Extract striding rq param calculation in function

net/mlx5e: Extract striding rq param calculation in function

Calculating parameters for striding rq is large enough
to deserve its own function. As the names are also very long
it is very easy to hit on the 80 char limitation every time
a change is made. This is an additional sign that it should
be extracted into its own function.

This patch has no functional change.
