Firmware events are queued up using the fw_event_work's struct work, not
its delayed_work member. The initial driver for SAS2 controllers had
handled firmware reset using the rescan barrier and was later redesigned
through "mpt2sas: [Resend] Host Reset code cleanup". The delayed_work
variables are now unused and may provoke CONFIG_DEBUG_OBJECTS_TIMERS
"assert_init not available" false warnings in
_scsih_fw_event_cleanup_queue.
Cleanup fw_event_work's unused entries, update it's kerneldoc, and update
_scsih_fw_event_cleanup_queue accordingly.
Fixes: 146b16c8071f (mpt3sas: Refcount fw_events and fix unsafe list usage)
