udev: downgrade message when we fail to set inotify watch up
    
    My logs are full of:
    
    systemd-udevd[6586]: seq 13515 queued, 'add' 'block'
    systemd-udevd[6586]: seq 13516 queued, 'change' 'block'

    systemd-udevd[9865]: IMPORT builtin 'blkid' fails: No such file or directory
    systemd-udevd[9865]: loop4: Failed to add device '/dev/loop4' to watch: No such file or directory
    (the last line is at error level).
    If we are too slow to set up a watch and the device is already gone by the time
    we try, this is not an error.
