agp: define proper stubs for empty helpers
The empty unmap_page_from_agp() macro causes a warning when building with 'make W=1' on a couple of architectures: drivers/char/agp/generic.c: In function 'agp_generic_destroy_page': drivers/char/agp/generic.c:1265:28: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 1265 | unmap_page_from_agp(page); Change the definitions to a 'do { } while (0)' construct to make these more reliable.
