sparc: Calculate the offset of the first variadic parameter correctly.

This was broken when rewriting stack frame handling. (b6787e36)
Though the below test case did not work before either, because the correct code path was not entered due to inspecting the wrong type.
The latter was accidentally corrected while getting rid of higher types. (ae42d217)
This fixes gcc/va-arg-12.c.
