GAS: Do not cancel initial offchannel wait with comeback delay 1

The minimum comeback delay 1 is used to indicate that fragmentation is
needed instead of indicating that the response is going to be available
only after some time. Do not cancel offchannel wait for this case
between the initial and comeback exchanges to avoid delaying the full
operation unnecessarily.
