net: skbuff: don't zero tc members when freeing skb
Not needed, only four cases:
- kfree_skb (or one of its aliases).
Don't need to zero, memory will be freed.
- kfree_skb_partial and head was stolen: memory will be freed.
- skb_morph: The skb header fields (including tc ones) will be
copied over from the 'to-be-morphed' skb right after
skb_release_head_state returns.
- skb_segment: Same as before, all the skb header
fields are copied over from the original skb right away.
