5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 554ec02c97254962bbb0a8776c3160d294fc7e51 ]
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.
