Coly Li 9dca4168a3 bcache: fix wrong bdev parameter when calling bio_alloc_clone() in do_bio_hook() 
Commit abfc426d1b ("block: pass a block_device to bio_clone_fast")
calls the modified bio_alloc_clone() in bcache code as:
	bio_init_clone(bio->bi_bdev, bio, orig_bio, GFP_NOIO);

But the first parameter is wrong, where bio->bi_bdev should be
orig_bio->bi_bdev. The wrong bi_bdev panics the kernel when submitting
cache bio.

This patch fixes the wrong bdev parameter usage and avoid the panic.

Fixes: abfc426d1b ("block: pass a block_device to bio_clone_fast")
