Properly take into account if we isolated a compound page during the
lumpy scan in reclaim and skip over the tail pages when encountered.
This corrects the values given to the tracepoint for number of lumpy
pages isolated and will avoid breaking the loop early if compound
pages smaller than the requested allocation size are requested.
