qmeventd: VMID from PID: don't fail immediately when encountering unexpected entry

Browse Source 
While such entries shuoldn't exist in practice without manually
messing around, it's not hard to imagine, and there's still a good
chance the actual VMID can still be found.

It's still unexpected to encounter such entries so keep the log line.
