Michael Lyle 5d62da3a8e bio: ensure __bio_clone_fast copies bi_partno 
commit 62530ed8b1d07a45dec94d46e521c0c6c2d476e6 upstream.

A new field was introduced in 74d46992e0d9, bi_partno, instead of using
bdev->bd_contains and encoding the partition information in the bi_bdev
field.  __bio_clone_fast was changed to copy the disk information, but
not the partition information.  At minimum, this regressed bcache and
caused data corruption.

Fixes: 74d46992e0d9 ("block: replace bi_bdev with a gendisk pointer and partitions index")
