fusion: fibre channel: correct out of order event processing

This patch corrects a problem in mptfc which can result in targets being removed after executing an "lsiutil 99" reset of the fibre channel ports.

The last rescan event was being processed before the setup reset work due to an inappropriate optimization in the event processing logic. Every rescan event is now queued for execution and the setup reset work now executes in the proper sequence.
