ia64: agp: Replace empty define with do while
It's dangerous to use empty code define.
Furthermore it lead to the following warning:
drivers/char/agp/generic.c: In function « agp_generic_destroy_page »:
drivers/char/agp/generic.c:1266:28: attention : suggest braces around empty body in an « if » statement [-Wempty-body]
So let's replace emptyness by "do {} while(0)"
