dfu: set poll timeout to 128 ms to reduce EPIPE errors
The previous 10 ms poll timeout creates ERROR_PIPE errors when the
octsim is connected to a more busy bus.
E.g. when a network device is connected to the same bus or when flashing
multiple OCTSIMs at the same time.
>From usb captures 70 ms should be already enough, but adding an additional
safety margin.
It is unclear why the EPIPE errors happens.
