usb: typec: ucsi: yoga-c630: fix error and remove paths
[ Upstream commit 168c3896f32e78e7b87f6aa9e85af36e47a9f96c ]
Fix memory leak and call ucsi_destroy() from the driver's remove
function and probe's error path in order to remove debugfs files and
free the memory. Also call yoga_c630_ec_unregister_notify() in the
probe's error path.
Fixes: 2ea6d07efe53 ("usb: typec: ucsi: add Lenovo Yoga C630 glue driver")
