commitdbe2518b2dupstream. When last descriptor in a descriptor list completed with XferComplete interrupt, core switching to handle next descriptor and assert BNA interrupt. Both these interrupts are set while dwc2_hsotg_epint() handler called. Each interrupt should be handled separately: first XferComplete interrupt then BNA interrupt, otherwise last completed transfer will not be giveback to function driver as completed request.
