Subject: [PATCH 2/42] 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.
