bcm63xx_enet: fix poll callback.
In case there was some tx buffer reclaimed and not enough rx packets
to consume the whole budget, napi_complete would not be called and
interrupts would be kept disabled, effectively resulting in the
network core never to call the poll callback again and no rx/tx
interrupts to be fired either.
Fix that by only accounting the rx work done in the poll callback.
