mm/page_alloc.c: rename check_free_page() to free_page_is_bad()
The name "check_free_page()" provides no information regarding its return
value when the page is indeed found to be bad.
Renaming it to "free_page_is_bad()" makes it clear that a `true' return
value means the page was bad.
And make it return a bool, not an int.
[akpm@linux-foundation.org: don't use bool as int]
