When monitors with same patterns are merged, BlueZ removes the existing
monitor from the kernel and re-registers it with updated/merged RSSI
parameters. The controller then triggers a new Device Found event for
the device that matches the updated monitor. Don't notify the D-Bus
client again with another DeviceFound for that device.
