usb: dwc2: Fix control OUT transfer issue

In buffer DMA mode, gadget should re-configure EP 0 to received SETUP
packets when doeptsiz.xfersize is equal to a setup packet size(8 bytes)
and EP 0 is in WAIT_FOR_SETUP state.

Since EP 0 is not enabled in WAIT_FOR_SETUP state, SETUP packets is NOT
received from RxFifo and wriiten to the external memory.
