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.
