block: fix __blkdev_get() for removable devices
Tejun Heo authored 
Commit 0762b8bd

 moved disk_get_part()
in front of recursive get on the whole disk, which caused removable
devices to try disk_get_part() before rescanning after a new media is
inserted, which might fail legit open attempts or give the old
partition.

This patch fixes the problem by moving disk_get_part() after
__blkdev_get() on the whole disk.

This problem was spotted by Borislav Petkov.
