    Downgrade a PROTOCOL_WARN log message.
    
    This one happens every time we get a failure from
    circuit_receive_relay_cell -- but for all the relevant failing cases
    in that function, we already log in that function.
    
    This resolves one case of #40400.  Two cases remain.

+  o Minor bugfixes (usability):
+    - Do not log "circuit_receive_relay_cell failed" at LOG_PROTOCOL_WARN;
+      instead log it at DEBUG. In every case where we would want to log
+      this as a protocol warning, we are already logging another warning
+      from inside circuit_receive_relay_cell. Fixes part of bug 40400;
+      bugfix on 0.1.1.9.
