ia64: fix set-but-unused warnings with syscalls
These macros often set up a variable that later macros sometimes do not use. Add unused attribute to avoid that. Similarly, the ia64 code tends to check the err field rather than the val (which is opposite of most arches) leading to the same kind of warning. Replace this with a dummy reference.
