CVE-2025-21675
net/mlx5: Clear port select structure when fail to create
Clear the port select structure on error so no stale values left after
definers are destroyed. That's because the mlx5_lag_destroy_definers()
always try to destroy all lag definers in the tt_map, so in the flow
below lag definers get double-destroyed and cause kernel crash:
mlx5_lag_port_sel_create()
mlx5_lag_create_definers()
mlx5_lag_create_definer()
