osd: clear PG_STATE_CLEAN when repair object

there is a race be found, when we repair object on clean state,
we queue a DoRecovery peering event, but before the peering event
dequeue,a snaptrim event on the missing object's snap dequeue,
then we will get pass the context< SnapTrimmer >().can_trim()
and go to get the context of the missing object(snapdir)

we can avoid this by clear clean state when we found missing..
