Related to #42640 The search/query plan holded a reference to schema, which could be destructed after schema change. This PR make plan hold a shared ptr to it fixing dangling reference problem under concurrent read & schema change. This PR also remove field binlog check for loading index for old segment with old schema may have binlog lack. Signed-off-by: Congqi Xia <congqi.xia@zilliz.com>
