lnwire: fail decoding on incorrect number of timestamps

Browse Source 
Currently if an incorrect number of timestamps is given, we fail later
on in the GossipSyncer. It makes more sense to fail right away, since we
already do that for incorrect SCID formats (e.g., unsorted or duplicate
SCIDs). There is already a matching check in Encode for incorrect number
of timestamps, so adding this check to Decode makes things symmetric.
