mm: page_alloc: rearrange watermark checking in get_page_from_freelist
Allocations that do not have to respect the watermarks are rare
high-priority events. Reorder the code such that per-zone dirty limits
and future checks important only to regular page allocations are ignored
in these extraordinary situations.
