net/mlx5e: Remove leftovers from old XSK queues enumeration
Before the cited commit, for N channels, a dedicated set of N queues was
created to support XSK, in indices [N, 2N-1], doubling the number of
queues.
In addition, changing the number of channels was prohibited, as it would
shift the indices.
Remove these two leftovers, as we moved XSK to a new queueing scheme,
starting from index 0.
Fixes: 3db4c85cde7a ("net/mlx5e: xsk: Use queue indices starting from 0 for XSK queues")
