md/raid5: ensure we create a unique name for kmem_cache when mddev has no gendisk
We will shortly allow md devices with no gendisk (they are attached to
a dm-target instead). That will cause mdname() to return 'mdX'.
There is one place where mdname really needs to be unique: when
creating the name for a slab cache.
So in that case, if there is no gendisk, you the address of the mddev
formatted in HEX to provide a unique name.
