net/mlx5e: CT: Fix freeing ct_label mapping

Add missing mapping remove call when removing ct rule,
as the mapping was allocated when ct rule was adding with ct_label.
Also there is a missing mapping remove call in error flow.

Fixes: 54b154ec ("net/mlx5e: CT: Map 128 bits labels to 32 bit map ID")
