usb: dwc3: gadget: synchronize_irq dwc irq in suspend
[ Upstream commit 01c10880d24291a96a4ab0da773e3c5ce4d12da8 ]

We see dwc3 endpoint stopped by unwanted irq during
suspend resume test, which is caused dwc3 ep can't be started
with error "No Resource".

Here, add synchronize_irq before suspend to sync the
pending IRQ handlers complete.
