Subject: [net 9/9] net/mlx5: fix error return code in mlx5e_tc_nic_init()

From: Wang Hai <wanghai38@...wei.com>

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: aedd133d17bc ("net/mlx5e: Support CT offload for tc nic flows")
