net/mlx5e: Fix wrong max num channels indication 

No XSK support in the enhanced IPoIB driver and representors.
Add a profile property to specify this, and enhance the logic
that calculates the max number of channels to take it into
account.

Fixes: db05815b36 ("net/mlx5e: Add XSK zero-copy support")
