usb: gadget: uvc: fix dropped frame after missed isoc

Browse Source 
With the re-use of the previous completion status in 0d1c407b1a
("usb: dwc3: gadget: Return proper request status") it could be possible
that the next frame would also get dropped if the current frame has a
missed isoc error. Ensure that an interrupt is requested for the start
of a new frame.

Fixes: fc78941d81 ("usb: gadget: uvc: decrease the interrupt load to a quarter")
