mpt3sas: Refcount fw_events and fix unsafe list usage
The fw_event_work struct is concurrently referenced at shutdown. Add a
refcount to protect it and refactor the code to use it.
Additionally, refactor _scsih_fw_event_cleanup_queue() such that it no
longer iterates over the list without holding the lock since
_firmware_event_work() concurrently deletes items from the list.
This patch is ported from commit 008549f6e8a1 ("mpt2sas: Refcount
fw_events and fix unsafe list usage"). These changes are also required
for mpt3sas.
