slub: fix leak of 'name' in sysfs_slab_add

The failure paths of sysfs_slab_add don't release the allocation of
'name' made by create_unique_id() a few lines above the context of the
diff below.  Create a common exit path to make it more obvious what
needs freeing.

[vdavydov@parallels.com: free the name only if !unmergeable]
