[lldb] Always log if acquiring packet sequence mutex fails

[teemperor]

Summary

Currently we only log in debug builds but I don't see why we would do this as this is neither
expensive and seems useful.

I looked into the git history of this code and it seems originally there was also an assert here
and the logging here was the #else branch branch for non-Debug builds.

         thread_ids.size() == 0 && IsConnected()) {
       thread_ids.push_back(1);
     }
   } else {
