commit801f614ba2upstream. Some NTFS volumes failed to mount because sparse data runs were not handled correctly during runlist unpacking. The code performed arithmetic on the special SPARSE_LCN64 marker, leading to invalid LCN values and mount errors. Add an explicit check for the case described above, marking the run as sparse without applying arithmetic.
