s3:libsmb: use tevent_req_defer_callback() unless there's only one request in cli_smb_received()

Callers of tevent_req_done() (or similar functions) have to return directly.
Otherwise the callback could invalidate the current stack state,
which is likely to trigger segfaults.

If there was only one pending request and we just got the response
for that one, we can use tevent_req_done() directly.

Otherwise there're more pending requests and we need to call
cli_state_receive_next() or we got the response for chained requests.
Both means that we have to use tevent_req_defer_callback().
