btrfs-progs: fi-usage: fix RAID10 raw disk usage
In case of RAID10, fi usage is reporting half the amount of allocated
space and twice the amount of unallocated disk space. Let's fix this.
For example, a RAID10 chunk of 3GiB with num_stripes 6, half of the
stripes (dev extents) are a mirror of the other half, so the 3GiB of
actual data has to be divided by 3, and not 6 to get the size of each of
those device extents.
