libpayload udc: Support legal edge case of GET_CONFIGURATION call

Hardware / Coreboot - Patrick Georgi [google.com] - 18 April 2015 01:42 UTC

I doubt anybody will ask for the configuration and request that 0 bytes be returned, but AFAICS that's legal, so let's support it.

Should have no effect on ChipIdea since it knows not to send more data than requested by the host.
