mlx4_en: don't use napi_synchronize inside mlx4_en_netpoll
commit c98235cb8584a72e95786e17d695a8e5fafcd766 upstream.
The mlx4 driver is triggering schedules while atomic inside
mlx4_en_netpoll:
spin_lock_irqsave(&cq->lock, flags);
napi_synchronize(&cq->napi);
^^^^^ msleep here
mlx4_en_process_rx_cq(dev, cq, 0);
spin_unlock_irqrestore(&cq->lock, flags);
This was part of a patch by Alexander Guller from Mellanox in 2011,
but it still isn't upstream.
