fs: check FAT cluster size
The cluster size specifies how many sectors make up a cluster. A
cluster size of zero makes no sense, as it would mean that the
cluster is made up of no sectors. This will later lead into a
division by zero in sect_to_clust(), so better take care of that
early.
The MAX_CLUSTSIZE define can reduced using a define to make some
room in low-memory system. Unfortunately if the code reads a
filesystem with a bigger cluster size it will overflow the buffer.
