staging: dwc2: use irq_return_t for interrupt handlers
The top-level hcd interrupt handlers already used irq_return_t, but the functions to which it delegates the actual work and the common irq handler returned plain ints. In addition, they used the IRQ_RETVAL in the wrong way (but because of the values of the various constants, this didn't result in wrong behaviour).
