platform/chrome: cros_ec_lpc - Use existing function to check EC result

Commit 6db07b633658 ("mfd: cros_ec: Check result code from EC messages")
added a common cros_ec_check_result() function that can be used to check
the ec_msg->result for errors and warns about them.

Use the existing function instead of duplicating same check in the driver.
