issue: #31480 #31481 release duplicate l0 segment task, which execute on old delegator may cause segment lack, and execute on new delegator may break new delegator's leader view. This PR skip release duplicate l0 segment by segment_checker, cause l0 segment will be released with unsub channel --------- Signed-off-by: Wei Liu <wei.liu@zilliz.com>
