fat: Update free_clusters even if it is untrusted
Currently, free_clusters is not updated until it is trusted, because Windows doesn't update it correctly. But if user is using FAT driver of Linux, it updates free_clusters correctly. Instead, this updates it even if it's untrusted, so if free_clustes is correct, now keep correct value.
