mon/PGMap: fix pgmap stat adjustment during map_pg_creates()

PGMonitor::map_pg_creates() is the only caller that passes sumonly=true,
which is necessary to avoid modifying creating_pgs while it is iterating
over it. However, everything else we *do* want to update--especially the
osd counts.

Rename the arg and skip only the creating bit.
