Subject: [net-next 05/10] net/mlx5e: Remove unused mlx5e_xsk_first_unused_channel

From: Maxim Mikityanskiy <maximmi@...lanox.com>

mlx5e_xsk_first_unused_channel is a leftover from old versions of the
first XSK commit, and it was never used. Remove it.

Fixes: db05815b36cb ("net/mlx5e: Add XSK zero-copy support")
