platform/chrome: cros_ec_lightbar: Fix response size initialization

Browse Source 
Commit 1e7913ff5f ("platform/chrome: cros_ec_lightbar: Reduce
ligthbar get version command") meant to set smaller values for both
request and response sizes.

However, it incorrectly assigned the response size to the `result` field
instead of `insize`.  Fix it.
