dwc_eth_qos: fix interrupt enable race
We currently enable interrupts before we enable NAPI. If an RX interrupt hits before we enabled NAPI then the NAPI callback is never called and we leave the hardware with RX interrupts disabled, which of course leads us to never handling received packets. Fix this by moving the interrupt enable to after we've enable NAPI and the reclaim tasklet.
