[PATCH] platform/chrome: cros_ec_lpc: Fix error code in cros_ec_lpc_mec_read_bytes()

[Dan Carpenter]

We changed these functions to returning negative error codes, but this
first error path was accidentally overlooked.  It leads to a Smatch
warning:

    drivers/platform/chrome/cros_ec_lpc.c:181 ec_response_timed_out()
    error: uninitialized symbol 'data'.

Fix this by returning the error code instead of success.

Fixes: 68dbac0a58ef ("platform/chrome: cros_ec_lpc: MEC access can return error code")
