features/marker-quota: reduce contributions to parents during unlink only if it is the last link.

- since we are not having different contributions for different (parent, name)
    pairs, but only for different parents, links present in the same directory
    will have only one contribution representing all of them. Hence parents will
    not be updated for each link call and parents account for just file-size
    instead of (numlinks * filesize). However this patch will cause issues
    for links present accross directories, as only one of their contributions
    is subtracted when all of them removed (Here all the links are accounted
    in their parents, thereby total size accounted is [numlinks * filesize]).
