Enguerrand de Ribaucourt 1bd66f1053 net: dp83822: disable rx error interrupt
commit 0e597e2affb90d6ea48df6890d882924acf71e19 upstream.

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.
