usb: typec: qcom-pmic: fix pdphy start() error handling
Move disabling of the vdd-pdphy supply to the start() function which
enabled it for symmetry and to make sure that it is disabled as intended
in all error paths of pmic_typec_pdphy_reset() (i.e. not just when
qcom_pmic_typec_pdphy_enable() fails).
Cc: stable+noautosel@kernel.org # Not needed in any stable release, just a minor bugfix
Fixes: a4422ff22142 ("usb: typec: qcom: Add Qualcomm PMIC Type-C driver")
