mptfusion: combine fw_event_work and its event_data
Tack the firmware reply event_data payload to the end of its
corresponding struct fw_event_work allocation. Rework fw_event_work
allocation calculations to include the event_data size where
appropriate.
This clarifies the code a bit and avoids the following smatch warnings:
drivers/message/fusion/mptsas.c:1003 mptsas_queue_device_delete()
error: memcpy() 'fw_event->event_data' too small (29 vs 36)
drivers/message/fusion/mptsas.c:1017 mptsas_queue_rescan() error: not
allocating enough data 168 vs 160
