The segment may be released before or during the request when delegator
tries to forward delete request to yet. Currently, these two situation
returns different error code.
In this particular case, `ErrSegmentNotLoaded` and `ErrSegmentNotFound`
shall both be ignored preventing return search service unavailable by
mistake.

Fix#28386
Current code snippet
```
// get delegator
sd, ok := node.delegators.Get(channel)
if !ok {
err := merr.WrapErrChannelNotFound(channel)
log.Warn("Query failed, failed to get shard delegator for search", zap.Error(err))
return nil, err
}
req, err = node.optimizeSearchParams(ctx, req, sd)
if err != nil {
log.Warn("failed to optimize search params", zap.Error(err))
return nil, err
}
// do search
results, err := sd.Search(searchCtx, req)
```
We could move these into `ShardDelegator`, and directly use sealed
segment num in `Search` methods, also segment num got outside could be
wrong when we specify partitions.

This check rejects load request if running out the pool workers, but
small segment would be loaded soon, another segments would been loading
again after a check interval, which leads to slow loading for collection
