net/mlx5: E-switch, enlarge peer miss group table

There is an implicit assumption that peer miss group table
require to handle only a single peer.
Also, there is an assumption that total_vports of the master
is greater or equal to the total_vports of each peer.
Change the code to support peer miss group for more than one peer.
