platform/chrome: cros_ec: remove unneeded label and if-condition

Browse Source 
Both `ec_dev->ec` and `ec_dev->pd` are initialized to NULL at the
beginning of cros_ec_register().  Also, platform_device_unregister()
takes care if the given platform_device is NULL.

Remove the unneeded goto-label and if-condition.
