usb: xhci: align PORTSC trace with one-based port numbering 



In the xHCI driver, port numbers are typically described using a one-based
index. However, tracing currently uses a zero-based index. To ensure
consistency between tracing and dynamic debugging, update the trace port
number to use a one-based index.
