usb: dwc3: gadget: Ignore ENDXFER completion for GSI endpoints



GSI endpoints do not generate a completion event for endxfer commands.
Upstream added a check for this event completion before continuing the
clear endpoint halt sequence.  Since this does not happen, skip the
check and continue with the clear halt command.
