usb: dwc3: Don't bail out in data stage completion if setup is pending



As per the control transfer programming model in SNPS data book if data
stage is successful move to status stage even if completed Data TRB status
indicates that setup pending bit is set. Hence do not give back ep0 usb
request with -ECONNRESET if setup pending bit is set and continue
interpreting data stage.
