ACPI / APEI: Generalise the estatus queue's notify code
Refactor the estatus queue's pool notification routine from
NOTIFY_NMI's handlers. This will allow another notification
method to use the estatus queue without duplicating this code.
Add rcu_read_lock()/rcu_read_unlock() around the list
list_for_each_entry_rcu() walker. These aren't strictly necessary as
the whole nmi_enter/nmi_exit() window is a spooky RCU read-side
critical section.
in_nmi_queue_one_entry() is separate from the rcu-list walker for a
later caller that doesn't need to walk a list.
