Christoph Hellwig 5ed964f8e5 mm: hide laptop_mode_wb_timer entirely behind the BDI API
Don't leak the detaіls of the timer into the block layer, instead
initialize the timer in bdi_alloc and delete it in bdi_unregister.
Note that this means the timer is initialized (but not armed) for
non-block queues as well now.
