fix: remove the streamingnode checking when loading segment (#45859)
issue: #43117

If we enable checking when loading segments, all segment should always
be loaded by streamingnode but not 2.5 querynode, make some search and
query failure when upgrading. Otherwise, some search and query result
will be wrong when upgrading. We choose to disable this checking for now
to promise available search and query when upgrading.

also see pr: #43346
