Restore the RECURSIONOK attribute after staleonly

Browse Source 
When doing a staleonly lookup we don't want to fallback to recursion.
After all, there are obviously problems with recursion, otherwise we
wouldn't do a staleonly lookup.

When resuming from recursion however, we should restore the
RECURSIONOK flag, allowing future required lookups for this client
to recurse.
