[opt](trino-connector) close scanner after finished

[morningman]

What problem does this PR solve?

The source should be closed after scanner is done to save memory.
Or there will be some objects remaining like:

  13:        192980        9263040  org.apache.kudu.client.RowwiseRowResult

Although these objects can be gc, eventually.
