Saravana Kannan 0c47d8a55f driver core: Fix locking bug in deferred_probe_timeout_work_func() ...

commit eed6e41813 upstream.

list_for_each_entry_safe() is only useful if we are deleting nodes in a
linked list within the loop. It doesn't protect against other threads
adding/deleting nodes to the list in parallel. We need to grab
deferred_probe_mutex when traversing the deferred_probe_pending_list.
