commit 8de2bd02439eb839a452a853c1004c2c45ff6fef upstream.
This reverts commit 923b2e30dc9cd05931da0f64e2e23d040865c035.
This is not a correct fix as TCA_EXT_WARN_MSG is not a hierarchy to TCA_ACT_TAB. I didn't notice the TC actions use different enum when adding TCA_EXT_WARN_MSG. To fix the difference I will add a new WARN enum in TCA_ROOT_MAX as Jamal suggested.
