Christoph Hellwig 77482c4dd4 block: clear ->slave_dir when dropping the main slave_dir reference
[ Upstream commit d90db3b1c8 ]

Zero out the pointer to ->slave_dir so that the holder code doesn't
incorrectly treat the object as alive when add_disk failed or after
del_gendisk was called.

Fixes: 89f871af1b ("dm: delay registering the gendisk")
