Fix: relayd: missing metadata stream causes all traces to be skipped

Commit 123ed7c22 intends for a trace that doesn't have a metadata
stream to be skipped when creating viewer streams. However, the loop
over ctf_traces should be "continued" rather then "broken" from when
this situation arises. Otherwise, all ctf_traces of the session are
skipped, which is not the intention here.

Moreover, a reference to the current ctf_trace is leaked when the
break (now continue) occurs.
