usb: dwc3: gadget: pre-issue Start Transfer for Interrupt EPs too 

Interrupt endpoints behave much like Bulk endpoints with the exception
that they are periodic. We can pre-issue Start Transfer exactly as we
do for Bulk endpoints.

While at that, remove one trailing blank line which is unnecessary.
