[PATCH] usb: typec: qcom-pmic-typec: avoid uninit values in dev_dbg() error paths

[Vasiliy Kovalev <kovalev@altlinux.org>]

Several functions take a 'goto done' shortcut on regmap_read() (or
switch default) failure before assigning locals that the trailing
dev_dbg() then formats.

Initialize the affected locals at declaration.

Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool.
