mon/PGMap: reweight::by_utilization - skip DNE osds

EC could set one or more members of acting set to CRUSH_ITEM_NONE,
which as a result can cause pgs_by_osd.resize() attempt to apply
for a large amount of memory which we can not afford.

Fix the above problem by always excluding a current DNE osd from
acting set.
