Christoph Hellwig 475bdd7544 block: clear ->slave_dir when dropping the main slave_dir reference ...

[ Upstream commit d90db3b1c8676bc88b4309c5a571333de2263b8e ]

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.
