IMPALA-14881: Fix instance id in scanner threads

Since IMPALA-6416 the instance id of new threads is inherited
from parent thread instead of setting explicitly. This is not
correct in case of scanner threads (mt_dop=0) when
HdfsScanNode::ThreadTokenAvailableCb is called through
ThreadResourcePool's callback where the thread can come from
an unrelated query.

Note that this issue only affects diagnostics.

Testing:
- tested manually by running parallel scan heavy queries and adding
  logging for fragment id in scanner thread - before the fix these
  log lines could contain two different instance ids
