This patch is to resolve some hangs we are seeing when doing PCI error injection to Mellanox Infiniband cards. With this patch we make mlx4 driver send an IB_EVENT_DEVICE_FATAL to the users and added this event to event handlers to avoid these hangs. If IPoIB is in connected mode, then added to cm an event handler and tried to make sure that when it sees the fatal event it does not try to send anymore packet because it will not receive any more completions or interrupts.
