Mentioned the starting sector when it overflows in mkntfs

Browse Source 
In an NTFS boot sector, the first sector of the partition is limited to
32 bits and it may overflow on large disks. This field is only used for
booting on the partition and it is ignored by ntfs-3g, but the warning
in mkntfs mislead users, so improve it.
