When tearing down the adapter for a reset, online/offline, or driver unload, the queue free routine would hit a GPF oops. This only occurs on conditions where the number of hardware queues created is fewer than the number of cpus in the system. In this condition cpus share a hardware queue. And of course, it's the 2nd cpu that shares a hardware that attempted to free it a second time and hit the oops. Fix by reworking the cpu to hardware queue mapping such that: Assignment of hardware queues to cpus occur in two passes: first pass: is first time assignment of a hardware queue to a cpu. This will set the LPFC_CPU_FIRST_IRQ flag for the cpu. second pass: for cpus that did not get a hardware queue they will be assigned one from a primary cpu (one set in first pass). Deletion of hardware queues is driven by cpu itteration, and queues will only be deleted if the LPFC_CPU_FIRST_IRQ flag is set. Also contains a few small cleanup fixes and a little better logging.
