    udisks2: Use device path to match mount points also
    
    Mount path is used to match mount points currently, however device
    path should be used also in order to be sure it is really corresponding
    mount point. Same mount path can be used for multiple mount entries
    (it is also used e.g. for autofs).
    
    $ mount | grep /media/test
    systemd-1 on /media/test type autofs ...
    localhost:/home/oholy on /media/test type nfs4 ...
