[fix](profile) close eof scanner before transfer done

[dataroaring]

We should close eof scanners before transfer done, otherwise, they are closed until scannode is closed. Because plan is closed after the plan is finished, so query profile would leak stats from scanners closed by scannode::close. e.g. SegmentTotalNum in profile is less.
