usb: xhci: remove obsolete sanity check debug messages

Remove debug messages that served as sanity checks during the initial
implementation phase of underrun/overrun completion codes. These checks
are now unnecessary.

Instead, improve the default debug messages for underrun/overrun events,
so that they are consistent with the reset of the completion codes.
