Fix an out of boundary access in fat.c
From SD Specifications Part2 - File System
For Next Free Cluster, value FFFFFFFFh indicates that there exists
no information about the first available (free) cluster. It is a
valid value. However fat.c doesn't check the value before use it
as array index. This will cause fsck_msdos coredump with some
micro sd cards
