btrfs-progs: Fix pointer math in __ino_to_path_fd

Browse Source 
We are casting an array of u64 values into a char ** array so
when we dereference this array (as a char **) on a 32 bit system
we're then re-casting that back to a 32 bit value. This causes
problems when we try to print those strings.
