block: display the correct diskname for bio
[ Upstream commit 9c0fb1e313aaf4e8edec22433c8b22dd308e466c ]
bio_devname use __bdevname to display the device name, and can
only show the major and minor of the part0,
Fix this by using disk_name to display the correct name.
Fixes: 74d46992e0d9 ("block: replace bi_bdev with a gendisk pointer and partitions index")
