    quota/marker: dir_count accounting is not atomic
    
    This is a backport of http://review.gluster.org/#/c/11694/
    
    Consider below scenario:
    
    Quota enabled on pre-existing data
    Now quota-crawl process will start healing xattrs
    Now if write is performed where healing is not complete, there is a
    possibility that 'update txn' is started before 'create xattr txn', in
    this case dir count can be missed on a dir where quota size xattr is not
    yet created.
    
    Solution is to get size xattr and if xattr is missing, add 1 for
    dir_count, this requires one additional fop if done in marker during
    each update iteration
    Better solution is to us xattrop GF_XATTROP_ADD_ARRAY64_WITH_DEFAULT
