net: sched: Add initial TC error skb drop reasons
Continue expanding Daniel's patch by adding new skb drop reasons that
are idiosyncratic to TC.
More specifically:
- SKB_DROP_REASON_TC_COOKIE_ERROR: An error occurred whilst
processing a tc ext cookie.
- SKB_DROP_REASON_TC_CHAIN_NOTFOUND: tc chain lookup failed.
- SKB_DROP_REASON_TC_RECLASSIFY_LOOP: tc exceeded max reclassify loop
iterations
