Christoph Hellwig d152c682f0 block: add an explicit ->disk backpointer to the request_queue 
Replace the magic lookup through the kobject tree with an explicit
backpointer, given that the device model links are set up and torn
down at times when I/O is still possible, leading to potential
NULL or invalid pointer dereferences.

Fixes: edb0872f44 ("block: move the bdi from the request_queue to the gendisk")
