Subject: net/mlx5e: Fix missing pedit action after ct clear action
Patch-mainline: v5.7-rc2
Git-commit: d5a3c2b640093c8a4bb5d76170a8f6c8c2eacc17
References: jsc#SLE-15172

With ct clear action we should not allocate the action in hw
and not release the mod_acts parsed in advance.
It will be done when handling the ct clear action.

Fixes: 1ef3018f5af3 ("net/mlx5e: CT: Support clear action")
