    xwayland: don't unlink lock file twice in stop function
    
    The stop function currently manually constructs the lock
    filename from the display number and also calls unlink
    on the same, already known lock filename from the manager
    struct.
    
    This commit gets rid fo the manual construction in favor
    of the saved lock filename.
