Fix off by one error in FAT16 <=> FAT32 detection

cluster_count is compared against FAT16_MAX, which is defined as 0xfff4
That is the maximum number of cluster a FAT16 can have.

For reference also check the  hardware whitepaper from Microsoft
FAT: General Overview of On-Disk Format, version 1.03 page 15
