mm/page_isolation: don't pass gfp flags to isolate_single_pageblock()

Patch series "mm/page_alloc: gfp flags cleanups for alloc_contig_*()", v2.

Let's clean up the gfp flags handling, and support __GFP_ZERO, such that we
can finally remove the TODO in memtrace code.

This patch (of 6):

The flags are no longer used, we can stop passing them to
isolate_single_pageblock().
