Christoph Hellwig 08fc1ab6d7 block: fix locking in bdev_del_partition
We need to hold the whole device bd_mutex to protect against
other thread concurrently deleting out partition before we get
to it, and thus causing a use after free.

Fixes: cddae808aeb7 ("block: pass a hd_struct to delete_partition")
