Peek messages example error: Return has 'timeout'. Should be 'reserved_count' instead.

Peek messages example return has 'timeout'. Should be 'reserved_count' instead.
Currently, the 'timeout' is not returned, 'reserved_count' is returned.
Peeking does not reserve the messages, so timeout information would not be usable - unless it was the time that the processing program still had left to finish with the message.
