mm/compaction: correct comment of candidate pfn in fast_isolate_freepages
Patch series "Two minor cleanups for compaction", v2.
This series contains two random cleanups for compaction.
This patch (of 2):
If no preferred one was not found, we will use candidate page with maximum
pfn > min_pfn which is saved in high_pfn. Correct "minimum" to "maximum
candidate" in comment.
