Feng Mingli cdfac2ac67 usb: dwc_otg_310: hcd: Giveback URB in tasklet context
In commit 94dfd7edfd ("USB: HCD: support giveback of URB in tasklet
context") support was added to give back the URB in tasklet context.
Let's take advantage of this in dwc_otg_310.

This speeds up the dwc_otg_310 interrupt handler considerably, it means
we've got a better chance of not missing SOF interrupts.

TEST=Unable to preview yuyv format usb camera on rk3288 board when use
dwc usb controller because of missing SOF interrupts.
