[PATCH] FAT: Use "unsigned int" for ->free_clusters and ->prev_free
This changes ->free_clusters and ->prev_free from "int" to "unsigned int".
These value should be never negative value (but it's using 0xffffffff(-1) as
undefined state).
With this changes, fatfs would handle the corruption of free_clusters
more proper.
