vendor_id and product_id information are not shown when displaying
multipath topology if the first path is down.
0QEMU_QEMU_HARDDISK_HELLOWORLD dm-0 , <--- Missing vendor and product

`-+- policy='service-time 0' prio=0 status=enabled
`- 2:0:1:0 sdd 8:48 active undef running
This happens because we only look at the first_path when printing the
topology. This patch looks at every slot in the path vector until we
find one with the correct value.
