patch 9.0.2141: [security]: buffer-overflow in suggest_trie_walk
Problem: [security]: buffer-overflow in suggest_trie_walk
Solution: Check n before using it as index into byts array
Basically, n as an index into the byts array, can point to beyond the byts
array. So let's double check, that n is within the expected range after
incrementing it from sp->ts_curi and bail out if it would be invalid.
Reported by @henices, thanks!
