Phillip Lougher 52e9ce1c0f Squashfs: fix corruption checks in squashfs_lookup() ...

The dir_count and size fields when read from disk are sanity
checked for correctness.  However, the sanity checks only check the
values are not greater than expected.  As dir_count and size were
incorrectly defined as signed ints, this can lead to corrupted values
appearing as negative which are not trapped.
