Subject: net/mlx5e: Remove unused mlx5e_xsk_first_unused_channel
Patch-mainline: v5.9-rc1
Git-commit: d39c9885b65740e737db8303ed3d344f2f6ceb35
References: jsc#SLE-15172
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")
