[PATCH] usb: typec: qcom-pmic: fix uninitialized value hdr_len and txbuf_len

[Rex Nie]

If the read of USB_PDPHY_RX_ACKNOWLEDGE_REG failed, then hdr_len and
txbuf_len are uninitialized. It makes no sense to print message header
and payload. It is also not safe to print uninitialized length of ram.
