    fsck_msdosfs: check next cluster index for validity before using it
    
    The boot->FSNext index can wind up to be out of range, thus leading to a
    segfault when trying to check whether it is pointing to a free cluster.
    Check for it being in range before using it as an index into the fat
    array.
