mkfs: fix bug in endianness at f2fs_update_nat_root

Browse Source 
This patch fixes a bug in the function "f2fs_update_nat_root", where the
access to the array "nat_blk->entries" was done using an index without
encapsulation of the "le32_to_cpu" macro.
The bug happens when trying to format an SD card in a powerpc architecture,
which natively runs at big-endian mode
