Revert "[PATCH] mm: micro optimise zone_watermark_ok"

This reverts commit e80ee884ae0e3794ef2b65a18a767d502ad712ee.

Pawel Sikora had a boot-time oops due to it - because the sign change
invalidates the following comparisons, since 'free_pages' can be
negative.

The micro-optimization just isn't worth it.
