net/mlx5e: TC, Refactor sample offload error flow
Refactor sample unoffload to be symmetric to sample offload. Use the existing del_post_rule() to release the post rule. Also mlx5e_tc_sample_unoffload() should not return post_rule which is NULL when post actions are supported. Sample offload works with this NULL because many places of the code use IS_ERR() instead of IS_ERR_OR_NULL() to check rule is valid and when rule is detected as sample offload the code is not using the rule. Let's be persistent and avoid returning NULL anyway and return the pre rule, like in CT case, which is not NULL.
