[PATCH 09/21] mm/page_alloc: Invert is_check_pages_enabled() check

[Brendan Jackman <jackmanb@google.com>]

A later patch will expand this function, making it ugly that the whole
body sits inside a conditional.

In preparation, invert it to de-indent the main logic. Separate commit
to make review easier.
