[PATCH] Get rid of arch_free_page() warning

[David Howells]

The attached patch gets rid of a warning produced when compiling
mm/page_alloc.c if the arch doesn't supply its own arch_free_page().

The problem is that there's one place in there that ignores the return value
of this function, and so you get a warning from gcc about an ineffectual
statement.
