ioc4: use static work_struct for ioc4_load_modules()
There is no reason to dynamically allocate work_struct for
ioc4_load_modules(). It makes the code more complex and makes it
impossible to flush the work directly. Use static work
ioc4_load_modules_work instead and flush it directly on exit.
This removes the use of flush_scheduled_work() which is being
deprecated.
