platform/chrome: cros_ec_ishtp: Fix UAF after unbinding driver
After unbinding the driver, another kthread `cros_ec_console_log_work`
is still accessing the device, resulting an UAF and crash.
The driver doesn't unregister the EC device in .remove() which should
shutdown sub-devices synchronously. Fix it.
