gossipd: fix excessive msg_queue length from status_trace()

Browse source 
When this (very spammy) "handle_recv_gossip" message was changed
from debug to trace, the suppression code wasn't updated: we suppress
overly active debug messages, but not trace messages.

This is the backtrace from an earlier version of the "too large queue"
patch:

```
