Subject: [PATCH 5.9 074/252] usb: dwc2: Avoid leaving the error_debugfs label unused

commit 190bb01b72d2d5c3654a03c42fb1ad0dc6114c79 upstream.

The error_debugfs label is only used when either
CONFIG_USB_DWC2_PERIPHERAL or CONFIG_USB_DWC2_DUAL_ROLE is enabled. Add
the same #if to the error_debugfs label itself as the code which uses
this label already has.

This avoids the following compiler warning:
  warning: label ‘error_debugfs’ defined but not used [-Wunused-label]
