dm: remove pointless kobject comparison in dm_get_from_kobject
The comparison is always true and the compiler optimizes it out anyway. Milan offered additional context relative to the original commit 784aae735d ("dm: add name and uuid to sysfs") which introduced the code: "I think it is just relict of some experiments before I committed this simple embedded sysfs kobj handling".
