Christoph Hellwig fc2454cc0c block: return -EBUSY when there are open partitions in blkdev_reread_part
[ Upstream commit 68e6582e8f2dc32fd2458b9926564faa1fb4560e ]

The switch to go through blkdev_get_by_dev means we now ignore the
return value from bdev_disk_changed in __blkdev_get.  Add a manual
check to restore the old semantics.

Fixes: 4601b4b130de ("block: reopen the device in blkdev_reread_part")
