Subject: [net-next 08/15] net/mlx5e: Remove incorrect debugfs_create_dir NULL check in TLS

From: Gal Pressman <gal@...dia.com>

Remove the NULL check on debugfs_create_dir() return value as the
function returns an ERR pointer on failure, not NULL.
The check is not replaced with a IS_ERR_OR_NULL() as
debugfs_create_file(), and debugfs functions in general don't need error
checking.
