Fix: UA3G read past end of tvb + NOE key descriptions
packet-ua3g.c:
Start tone device routing packet causes exception because it adds a subtree with
length 6 where it should be 3. Changed 6 to 3.
packet-noe.c:
Key description is incomplete because buffer reserved is only 10 bytes long and
key descriptions are up to 23 bytes long. Changed buffer length to 24.
Bug: 13502
