devmon: assert condition immediately if device already exists

  1. udev fires early, creates device nodes in /dev/                                                                                                           
  2. Config is parsed later, calling devmon_add_cond() for each dev/ condition
  3. At this point the device already exists but the inotify event was missed
  4. The PR's fexist() check catches this — new node is added to the TAILQ and condition is immediately asserted
