usb: dwc3: gadget: Fail request submission if it was already queued
Function driver should not try to queue a busy request again to DCD
until DCD returns it by calling its completion handler or it is
explicitly dequeued. Some buggy function driver may try to submit a
request again which is with DCD resulting in corruption of request_list
leading to crash later in giveback. Catch such conditions and fail the
request submission to DCD.
