atm: he: Fix undefined sequence points.
GCC complains in these queue index operations because we perform operations of the form: x = some_operation(++x); which is undefined. Replace with: x = some_operation(x + 1); which is well defined and provides the intended operation. Signed-off-by: David S. Miller <davem@davemloft.net>
