    propfind: calculate quota for the appropriate resource
    
    Currently, available quota is calculated for the root.
    However, if the resource resides e.g. on a different partition
    because of symlinks, the returned value is incorrect.
    
    According to [0], the calculation for used quota might be left
    as it is, but let's change it as well, for the sake of consistency.
