[0/2] usb: typec: qcom-pmic: fix use-after-free on late probe errors

When reviewing a patch updating the qcom-pmic typec driver, I noticed
that the error handling is broken and can lead to use-after-free.

This series addresses the use-after-free and also fixes the error
handling in the pdphy_start() callback which failed to disable its
supply in all error paths.

The latter fix is not marked for stable on purpose as its not a critical
fix (I'm sure autosel will disagree).
