usb: dwc2: gadget: Fix GOUTNAK flow for Slave mode.
Because of dwc2_hsotg_ep_stop_xfr() function uses poll
mode, first need to mask GINTSTS_GOUTNAKEFF interrupt.
In Slave mode GINTSTS_GOUTNAKEFF interrupt will be
aserted only after pop OUT NAK status packet from RxFIFO.
In dwc2_hsotg_ep_sethalt() function before setting
DCTL_SGOUTNAK need to unmask GOUTNAKEFF interrupt.
Tested by USBCV CH9 and MSC tests set in Slave, BDMA and DDMA.
All tests are passed.
Fixes: a4f827714539a ("usb: dwc2: gadget: Disable enabled HW endpoint in dwc2_hsotg_ep_disable")
Fixes: 6070636c4918c ("usb: dwc2: Fix Stalling a Non-Isochronous OUT EP")
