mm/page_alloc: refactor the initial compaction handling
The initial direct compaction done in some cases in
__alloc_pages_slowpath() stands out from the main retry loop of reclaim +
compaction.
We can simplify this by instead skipping the initial reclaim attempt via a
new local variable compact_first, and handle the compact_prority as
necessary to match the original behavior. No functional change intended.
