chromeec: correct response length for VBNV write
The EC doesn't return any data when one performs a write to VBNV context. Therefore there is a mismatch of expectations. Correct this by properly setting the expected response length. BUG=chrome-os-partner:31148 BRANCH=None TEST=No longer hanging while writing to VBNV on ryu.
