usb: dwc2: gadget: Fixes for StsPhseRcvd interrupt
The StsPhseRcvd interrupt should not be enabled in slave mode. Also move the StsPhsRcvd interrupt checking in the endpoint interrupt handler to the correct order according to the databook. The interrupt itself will be implemented in a later commit.
