Subject: alpha: agp: make empty macros use do-while-0 style
Copy these macros from ia64/include/asm/agp.h to avoid the
"empty-body" in 'if' statment warning.
drivers/char/agp/generic.c: In function 'agp_generic_destroy_page':
../drivers/char/agp/generic.c:1265:42: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
1265 | unmap_page_from_agp(page);
