net: dp83822: disable rx error interrupt
Some RX errors, notably when disconnecting the cable, increase the RCSR
register. Once half full (0x7fff), an interrupt flood is generated. I
measured ~3k/s interrupts even after the RX errors transfer was
stopped.
Since we don't read and clear the RCSR register, we should disable this
interrupt.
