[SCSI] mpt2sas: fix hotplug event processing
Here's a fix for hotplug events. The useage of queue_delayed_work seems to broke the fifo for processing of firmware events. After several iterations of adding and removing cabling connected to jbods, the devices are not getting added becuase kernel thread is activited out of order.
