[PATCH 1/2] i2c: cros-ec-tunnel: Fix usage of cros_ec_cmd_xfer()

[Brian Norris]

cros_ec_cmd_xfer returns success status if the command transport
completes successfully, but the execution result is incorrectly ignored.
In many cases, the execution result is assumed to be successful, leading
to ignored errors and operating on uninitialized data.

We've recently introduced the cros_ec_cmd_xfer_status() helper to avoid these
problems. Let's use it.
