usb: dwc3: gadget: Return proper request status
commit c7428dbddcf4ea1919e1c8e15f715b94ca359268 upstream.
If the user sets the usb_request's no_interrupt, then there will be no
completion event for the request. Currently the driver incorrectly uses
the event status of a different request to report the status for a
request with no_interrupt. The dwc3 driver needs to check the TRB status
associated with the request when reporting its status.
Note: this is only applicable to missed_isoc TRB completion status, but
the other status are also listed for completeness/documentation.
Fixes: 6d8a019614f3 ("usb: dwc3: gadget: check for Missed Isoc from event status")
