As follows:
for (auto i = callbacks_for_degraded_object.begin(); i != callbacks_for_degraded_object.end();) {
finish_degraded_object((i++)->first);
}
void PrimaryLogPG::finish_degraded_object(const hobject_t oid)
{
if (callbacks_for_degraded_object.count(oid)) {
contexts.swap(callbacks_for_degraded_object[oid]);
callbacks_for_degraded_object.erase(oid); // Release
}
map<hobject_t, snapid_t>::iterator i = objects_blocked_on_degraded_snap.find(
oid.get_head()); // Access

(cherry picked from commit 86d55c1)
Conflicts: src/osd/PGBackend.h: `PrimaryLogPG` derives from
`PGBackend::Listener` in mimic, and it's `PGBackend::Listener` 's only
derived class. so we need to update `PGBackend::Listener` accordingly.
