net: bcmgenet: complete Tx NAPI after one reclaim pass

Browse source

After reclaiming, the Tx poll asks to be polled again. That extra poll
finds nothing to do and does not reduce the interrupt rate.

Complete the NAPI and unmask the ring interrupt right after the reclaim.

On a CM4 this raises 60 byte pktgen Tx from about 187k to 224k pps and
saves about 5% of one core at TCP line rate.
