makedevs: Create blocks of devices with the correct uid/gid

makedevs: Create blocks of devices with the correct uid/gid

When creating a block of devices (i.e., when count > 0), the wrong
path was used with the call to chown(), effectively trying to change
the owner of some (probably) non-existent file. Thus the created
device nodes were always owned by root.
