[PATCH] platform/chrome: cros_ec_lightbar: Fix response size initialization

[Tzung-Bi Shih <tzungbi@kernel.org>]

Commit 1e7913ff5f9f ("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.

As the cut-off date for the next merge window is approaching.  I really
hope to include the fix in the cycle.  Sent the fix by myself.  See also
