Scan of services after connecting to DFUTarg does not return
the new services on the device. Instead the old services that existed
on the device before going into DFU mode are returned.
Device side trace shows it was actually in DFU mode.
Same device with nRFConnect works from Android 7.1 and 7.1.1
