usb: dwc3: Avoid unmapping USB requests if endxfer is not complete
If DWC3_EP_DELAYED_STOP is set during stop active transfers, then do not
continue attempting to unmap request buffers during dwc3_remove_requests().
This can lead to SMMU faults, as the controller has not stopped the
processing of the TRB. Defer this sequence to the EP0 out start, which
ensures that there are no pending SETUP transactions before issuing the
endxfer.
