net/mlx4_en: remove NETDEV_TX_BUSY
Drivers should avoid NETDEV_TX_BUSY as much as possible.
They should stop the tx queue before qdisc even tries to push another
packet, to avoid requeues.
For a driver supporting skb->xmit_more, this is likely to be a prereq
anyway, otherwise we could have a tx deadlock : We need to force a
doorbell if TX ring is full.
