squashfs: Fix integer overflow in sqfs_inode_size() A carefully crafted squashfs filesystem can exhibit an extremly large inode size and overflow the calculation in sqfs_inode_size(). As a consequence, the squashfs driver will read from wrong locations. Fix by using __builtin_add_overflow() to detect the overflow.
