tftp: check for Option Acknowledgements
TFTP Option Acknowledgement packets were being excluded.
When a read/write request contains options, an Option Acknowledgement
is returned that contains the option strings that the transaction
will use.
The options sent in the request are not compared with what was
acknowledged.
